Yes, I think it should be there. Unfortunately. The most important issue, I think, is to find out/code/propose a replacement for utmp. utmp is old, and is one of the old *IX utilities that did not age well. When *IX moved from being a pure/mostly command line system, there was nothing to replace utmp to find out who is logged in -- or, better saying, nothing that really won the battle. We now need a similar thing that will work on graphical environments. We need to be able to know who is logged in, if a movie is being played, etc. utmp does not cut it, but there is nothing I know of (a bit dated as well, last time I looked for it was a few years ago) that cut the mustard. The issue we have is less and less programs bother about utmp; some that do bother to write a login record in utmp do not bother to write a "logoff" (usually not really a logoff, but an exit from the application). FWIW, utmp is in Posix. Cheers, ..C..
