At least one user reported there being a problem with a `squid' user
in the past.  I know of a couple of people (including myself) who
had a conflict when NetBSD added a `named' and `ntpd' user.

No, but it's good prior art from FreeBSD/OpenBSD.
At least, in my 15 years involved in system administration across
a diverse range of sites I've never seen the practice before.

That for tech-pkg to consider, but I would suggest that 'yes' is the
answer.
