Okay, but the point I'm trying to make here is that if you have "for a
very long time" patched the sources to allow it, you know where the
check comes from. I'm not saying you were being deliberately misleading,
but it was still confusing nonetheless -- and personally, I eventually
found where it was being enforced by checking Debian's shadow package to
see which new features they patched in downstream.
BTW I'm serious about using the GECOS field for the display name, you
could for example use the following in your .profile:
REALNAME=$(getent passwd "$USER" | cut -d: -f5 | cut -d, -f1 )
And then embed that in your prompt string.
