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.

I have written a JVM in Rust
Great learning project, I'm glad the author is having fun.
If they're interested in bolting on a GC, it couldn't hurt to look at MMtk. (https://www.mmtk.io/) Some high quality collection algorithms, written to be pluggable to various VMs, and written in Rust.

Writing a Compiler and a Virtual Machine in Rust
just here to mention https://github.com/mmtk/mmtk-core crate which provides garbage collectors. The only problem is requiring threads, which makes it unsuitable for wasm.

JDK 20 G1/Parallel/Serial GC Changes
AFAIK, no. The opposite is true with MMtk (https://www.mmtk.io), which is a toolkit with many GC algorithms implemented that has been plugged into other runtimes, including, as it happens, OpenJDK.

Garbage Collection with LLVM
IME the MPS is hard to set up correctly, and I've heard in Clasp they got in performance trouble, as per-thread allocation buffers were too small and they couldn't make the buffers larger. But indeed being conservative on the stack is a fine choice; someone mentioned Boehm being easy to use, and the MMTk is a newer option which allows for bump-allocation and being precise on the heap (like MPS), but at the moment you have to provide your own stack scanning code.

As part of the stdlib mutex overhaul, std::sync::Mutex on Linux now has competitive performance with parking_lot
Recently I learned about the hyaline reclamation scheme that seize uses. Mentioning since it may interest you:flurry, a concurrent HashMap, recently switched from crossbeam-epoch (based on epoch GC) to seize.
