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.

Rust fact vs. fiction: 5 Insights from Google's Rust journey in 2022
I do not have as strong of feelings as your parent, but:
1. A lot of the APIs make use of the typestate pattern, which is nice, but also very verbose, and might turn many people off.
2. The generated API documentation for the lower level crates relies on you knowing the feel for how it generates the various APIs. It can take some time to get used to, especially if you're used to the better documentation of the broader ecosystem.
3. A bunch of the ecosystem crates assume the "I am running one program in ring0" kind of thing, and not "I have an RTOS" sort of case. See the discussion in https://github.com/rust-embedded/cortex-m/issues/233 for example.

A GPIO Driver in Rust
I don't think so. Once a function is compiled, it basically becomes a black box with a type signature so unless sleeping in a function affects its signature, that information is erased. If you pass in some kind of a sleep token that has to be used to sleep, then yeah I think you could enforce it by only being able to get that token in a non-atomic context and making it leak proof.
The Cortex-M crate does something similar, but for proving that you are in an atomic context. Another function that expects a CriticalSection type is then assured that it's running without interrupts enabled.

Use a custom linker script with lld
I advise you to look at how runtimes for embedded systems work (look at this on for example), as they also make heavy usage of linker scripts.
