Agreed. I find it quite rare to find something that does not build on MUSL. When I do, it is software that goes out of its way to abuse GNU specific stuff.

The most common problem for me is software distributed as binary that links to Glibc. That shows up on surprise places. For example, building the Ladybird browser uses vcpkg which needs Glibc. In these cases, I reach for Distrobox.

Pretty sure the DNs behaviour in MUSL was changed and is no longer an issue.
