That name is from "mkpath gives its result in a static buffer and
forces the callers to xstrdup() if they want to keep the result;
this is a thin wrapper to do so for the caller".  As there is no
str_fmt() that gives its result in a static, so...

Yes, it is annoying.

If we twist the logic behind the 'mkpathdup' name a little bit,
perhaps we can call it sprintf_dup or something.  That is, "sprintf
wants a fixed preallocated piece of memory to print into, and we
relieve the callers of having to do so", perhaps?

dprintf, mprintf, etc. are also fine by me.
