I'm not sure. They seem to be of limited usefulness - UTF-16 is legacy, and UTF-32 is the same as wchar_t on any implementation that actually supports UTF-32 (at least wchar_t has to cover the whole Unicode codepoint space, so 16-bit is out and the only reason it could be anything other than UTF-32 is gratuitous incompatibility). Of course we'll support this if it's standardized as a required interface for future C versions, but I'm not sure it's in line with musl's philosophy or criteria for inclusion to be trying to advance these interfaces into a standard without a good argument that they're important to have (if you believe they are, I'm open to hearing that and seeing what others think).
