For point one, it helps that Rust is one of the easiest languages I have ever worked with to install the compiler run-time, pull dependencies, build, run, and distribute. So at the very least, it won't get in your way if you just want to distribute a static binary, or give your users a few commands to compile it themselves, even if it is "some weird language". On point two, Rust is not a moving target, in the sense that it has maintained back compatibility since release to an amazing degree, and the build system does a good job by automatically pinning dependencies for applications. Also, even if it is totally abandoned, you still have a pretty solid language with C-like performance that benefits from ongoing LLVM optimizations. But it is certainly true that there could be unfixed bugs in an abandoned Rust.
