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.

b2 for C++?
Yes, this is a common stumbling block for users with the CMake background. The underlying reason is that build2 is a "multi-repo first" build system while CMake is "mono-repo first" (or perhaps even "mono-repo only"; I don't think there were repositories as we know them when Autotools was designed ;-)). In particular, in build2 it's common to build multiple independent projects/repositories in a shared build configuration. Putting this build configuration as a subdirectory of source directory of one of them would be strange. You can read more on this in this issue: https://github.com/build2/build2/issues/187

build2 IDE support?
build2 can generate Clang compilation database (currently indirectly): https://github.com/build2/build2/issues/96 I believe quite a few IDEs (including CLion) can work off that.

Debian Running on Rust Coreutils
Yes, please, that would be very helpful: https://github.com/build2/build2/issues

The Linux Kernel Prepares for Rust 1.77 Upgrade
This is a good guide on building small Rust binaries: https://github.com/johnthagen/min-sized-rust
This talks about going to extreme lengths on making the smallest Rust binary possible, 400 bytes when it was written, https://darkcoding.net/software/a-very-small-rust-binary-ind...
The thing is, you lose a lot of nice features when you do this, like panic unwinding, debug symbols, stdlib… for kernel and some embedded development it’s definitely important, but for most use cases, does it matter?

Rust wont save us, but its ideas will
Oh it was 137, haha. I will link you to this older comment of mine: https://news.ycombinator.com/item?id=29408906

Making Rust binaries smaller by default
Are you sure? If so then this is awesome news, but I'm a bit confused; the commit in that min-sized-rust repo adding `build-std` to the README was merged in August 2021: https://github.com/johnthagen/min-sized-rust/pull/30
Are you saying that at that point the feature still hadn't "landed in Rust nightly" until recently? If so then what's the difference between a feature just being available in Rust nightly, vs having "landed"?

Was Rust Worth It?
Rust binaries are by default nowhere close to 500MB. If they are not small enough for you, you can try https://github.com/johnthagen/min-sized-rust. By avoiding the formatting machinery and using `panic_immediate_abort` you can get about the size of C binaries.

Tiny Binaries (2021)
That must be without stripping. Also there are ways to reduce binary size. See e.g. [min-sized-rust](https://github.com/johnthagen/min-sized-rust). I've gotten stripped binaries of small cli utils less than 400KiB without doing anything special, less than 150 KiB by customizing profile settings and compressing with upx, and less than 30 KiB by replacing the std with the libc as the link shows. Haven't tried with fltk though...

Shared libraries
This is not quite what you're asking, but it does also address the underlying concern: https://github.com/johnthagen/min-sized-rust
What are some alternatives?

smartstring - Compact inlined strings for Rust.
embedded-graphics - A no_std graphics library for embedded applications
Cargo - The Rust package manager
BSDCoreUtils - BSD coreutils is a port of many utilities from BSD to Linux and macOS.
