Updating utmp/wtmp is not only for 'keeping track of sessions', it is
also used by shutdown and other systems to know who to notify when
taking down a host or notify logged in users in other cases. If NX do
not update utmp/wtmp for logged in users, I would claim that NX is
broken, and if it is by design, then NX is broken by design.
