Musl 1.2.4 adds TCP DNS fallback

IIRC this was causing some exotic problems when deploying docker images based on musl.

I think there's also still some potential problems because it still does some things differently than glibc. Musl defaults to parallel requests if you define more than one nameserver (multiple --dns=, for example, for the docker daemon)...where glibc uses them in the order you provide them.

To be clear, that's not "wrong", but just different maybe from what docker was expecting.

I really hope it does some things differently than glibc: https://sourceware.org/bugzilla/show_bug.cgi?id=19643

In any case glibc uses NSS, so what glibc does depends on the configuration. It may well just forward the request to systemd-resolved.
