Since what version does Windows have a reset option? For dozens of
years, literally, Windows has been notorious for leftovers of removed
programs remaining in the "base system" and causing unexpected effects.
There were even commercial products on the market to purge those leftovers.

FreeBSD is different in this respect. No part of third-party software
ever gets into the base system (unless you install something manually
and incorrectly). And of course you don't lose any user data if you run 
"pkg delete -a"

Well, I was not feeling particulary sysadmin-ish about the desktop
system I wanted to cleanup.

Dare I say that one needs knowledge beyond a regular user to understand
these subtleties?

Is the /usr/sbin/policy-rc.d method still the official supported one of
disabling this behavior when it is not desirable?
