Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Flattening ASTs (and Other Compiler Data Structures)
I used such a succinct AST structure to implement a JavaScript parser and interpreter for a severely memory constrained environment (embedded): V7 (https://github.com/cesanta/v7)
We later switched to a ast->bytecode compilation step but for a while the implicit AST was directly traversed during interpretation.

Microvium Is Small
Nice! A few years ago I took a stab at this problem space with https://github.com/cesanta/v7 ; with fun tricks like in-place compacting GC, stdlib JS object graph "frozen" in rom etc

JavaScript Is Weird
https://github.com/cesanta/v7
Languages are not all equal nor do they all function in the same way, and that's not my opinion.
Javascript syntax itself is one thing, and you can certainly feel free to Javascriptify some C++ libraries and make it all look a certain way for specific tasks, while managing things behind the scenes, up to a point... but there is no getting around the fact that SOMEONE and some languages are needed to implement low level systems functionality.
the power of Cython or the Python C FFI is that it allows you to script/glue modular native code.
You then state "C++14 may have been ratified 7 years ago but it's not the target code your build chain spits out"
no, a C++ COMPILER spits out assembler code that then gets assembled and linked into an executable.
The C++ or C code corresponds directly to a given set of assembler instructions which correspond directly to CPU instructions.
You claim that Python programming of microcontrollers is mainstream, but this is not true nor possible. Python SCRIPTING of code modules (that cannot be written in Python) is certainly one way to assemble a system from pre-built legos.
If you refer to knowing what I'm talking about as gatekeeping and egoism, might I suggest that you insist less forcefully in the correctness of incorrect things you state? we could be done with this spat in short order if YOU would refrain from speaking falsehoods. lies.untrue things.
I look forward to your lisp c compiler. make sure that it's 100% lisp from the bottom up, or I'll consider you're having ceded my point. Consider that the lisp you author in has a garbage collection system that lisp cannot have written originally, nor has any semantics for the underlying memory structures of, but hey, I guess if one is committed to pretending that all languages are equal for all tasks, who am I to question ones self-identification with a given language.

Running the "Reflections on Trusting Trust" Compiler
The C4 compiler [https://github.com/rswier/c4] is a self-hosting compiler for a subset of the C programming language that produces executable x86 code. You can understand and audit this code in a couple of hours (its 528 lines).
It could be an interesting exercise to bootstrap up from something like this to a working linux environment based solely on source code compilation : no binary inputs. Of course a full linux environment has way too much source code for one person or team to audit, but at least it rules out RoTT style binary compiler contamination.

Flattening ASTs (and Other Compiler Data Structures)
I was surprised to see nodes still have two pointers ("references") given that you now know that that the first pointer will always point exactly to the next node. I've see https://github.com/rswier/c4 use that. Granted it doesn't make for the most readable code, but it's even smaller and faster.

vermin_vm: Virtual Machine(~400 lines) + Assembler(~800 lines) written in C
VMs with simple instruction sets is a fun topic. Some years ago I got inspired by the amazing rswier/c4 compiler by Robert Swierczek and explored the smallest instruction set I could get away with to create VMs that could run non-trivial workloads.

Hand-optimizing the TCC code generator
C4 comes to mind (C in 4 functions), https://github.com/rswier/c4.
have you considered adding a backend for LLVM? perhaps a bit heavyweight, but it could be a good way to get C/C++, fortran, rust, etc. if that's something you'd like!

Some people of the Linux Community in a nutshell
I use Alpine Linux (no GNU bloat btw), dwm (Sucks less!), and I edit all my C (no bloat language) through busybox ed and compile my programs with (c4)[https://github.com/rswier/c4]

which programming language was used to make c++ compiler?
Keep in mind you can create a "usable" C compiler by yourself, and is doable in surprisingly low amount of code. Try https://github.com/rswier/c4/blob/master/c4.c
