(that was quoting xterm's manpage)
fwiw xterm relies upon utempter to do what's appropriate.
In a quick check, that's since
Patch #188 - 2004/5/12 - XFree86 4.4.99.6
* improve ifdef's for utempter library to omit direct calls to
setutent() or getutent() (adapted from patch by Christian Biere).
The README for utempter says
The utempter is a privileged helper used by libutempter library to
manipulate
utmp and wtmp files.
and (the documentation appears to be written in C) the last thing utempter
does if no errors stop it is this:
(void) updwtmp(_PATH_WTMP, &ut);
utempter uses setgid, while systemd (whose documentation is per-line of
code no better than utempter) appears to require root privilege
(which of course is a big step backwards).
