The issue I have with this solution is that it requires the 'who'

Maybe filter them out if their login shell ends in "/nologin"?
Also, I guess this is mostly theoretical, but you would want to show
'gdm-greeter' if a user actually named themselves that.
The "/nologin" hack should work in that weird case.
Why not check for class == user?
Oh, I never knew about sd_session_get_class. Yes, it sounds like
Gnulib's readutmp.c should use this function to filter out bogus entries.
There's clearly already attempts to do this in the code, so it's worth
debugging what goes wrong there. Sorry if I'm missing something
obvious.
Currently the Gnulib code checks only for class being "manager". I
wonder why it does that? Anyway, it appears that 'who' should output
only "user" entries.
