The problem is less locking out than stupid software. I've seen software
that verifies the grants priviledges by checking for root uid, root gid,
root uid and gid, username root, username root and uid. The weirdness price
is granted to the piece of software that only works if the username <->
uid relation is bijective ... I can only hope that stuff has now been fixed
since I ran into a lot of that braindamage during the early stages of the 68k
userland work but not again during the MIPS port.
In any case I'd recommend to consider the username root and uid 0 as toxic
waste even with POSIX 1003.1e/2c security enabled, there is just too much
braindead software out there.
