I'm still dealing with figuring out how to dodge regreSSHion on Windows so this piqued my interest, I haven't had the occasion to compare glibc and musl, but this post is illuminating [0]
Honestly, I have had very few issues with it. Generally for the big issues there compatibly layer packages available, e.g. you can install a musl-fts package since musl doesn't implement fts.
I think there is value in a cleaner, newer, more minimal c library. Pretty much everything just works, and for what doesn't I either compile statically in a devuan container or use a flatpak.
