I would hazard the guess that that’s perfectly fine. Desirable even. People who run scratch or alpine images and link against musl aren’t usually looking to write desktop applications or video games.
With glibc that is a pain, I need to build in a container with tthe oldest glibc I want to support, and that still doesn't cover Alpine. And I dont know if a static musl build would even work for that either (if I need to be able to load GUI libraries).
