The advantage is that getpwent and getgrent are more portable, of

Only Posix systems can be trusted to actually have /etc/passwd and
/etc/groups.  On systems where these files are absent, we can still
have the C APIs (or craft our owns inside Emacs, as w32.c does).

That is not to say we should necessarily add these APIs, if they
currently don't have any callers within Emacs.
