Yep. There are lots of edge-cases and macros that glibc provides are difficult to emulate because they require a lot of domain-specific knowledge and special handling. There isn't really a way to use musl in any large distro without lots and lots of patching and giving up correctness and completeness. It's akin to not using ICU4{C,J} and praying that simplistic Unicode handling like normalization will magically work. Using musl is fine for limited uses, but it's magical thinking to believe that it's at exact feature and functional parity replacement for glibc.
