Yes - I seem to remember that V7 and also 4.1, 4.2 BSD shipped with
several such pseudo-users, although they may've been a local addition at
the university where I used them in the early 1980s.
They are good for environments with users you don't trust but who have
to be able to do specific admin tasks... but they could for sure be
added locally in those environments.
Of course, if you have a university with 5,000 workstations, it'd be
nice not to have to make changes to each of them... but, it's likely
that changes are already made, and if one of them is to enable NIS then
you can add the pseudo-users globally anyway.
Every account is a potential break-in vector, however unlikely, so it
seems better not to ship with them.
