The Single UNIX  Specification, Version 2, has migrated to <utmpx.h>,
and defines: endutxent, getutxent, getutxid, getutxline, pututxline,
setutxent.  These could be implemented on top of utmp(5), but I think it
would be better to migrate the "binary" format to one that's also
extensible.

Unfortunately it doesn't define a function to set the filename for an
alternate user accounting database, a feature also missing from the
getpent() family (but not missing on SunOS-5, IRRC).

Migrating NetBSD to <utmpx.h> might also mitigate some of the problems
with UT_NAMESIZE limits mentioned recently in a couple of PRs.
