While I agree generally, statically linking Lua(TeX), means losing the
support for loading C modules, which requires a dynamic linker. And IIRC
networking (with luasocket in LuaTeX) also depends on dynamic libraries
(NSS) in normal glibc systems -- i.e. the statically linked musl binaries
would not respect the system settings.
I think that the only use of C modules in TeX Live itself is in PGF/TikZ
(although this still must be set up manually by the user?).
But there are users that use modules outside of TeX Live as well. E.g.
