I would consider vipw more authoritative. Certainly, I wouldn't like
vipw to barf because useradd allowed me to produce an invalid password
file (it becomes much more difficult to fix).
My criterion would be whether unrecoverable errors could be produced by
relaxing checks in changing the password file (like locking the system
against administrator access, needing an extremely inconvenient reboot
to gain access) or whether the result is merely some stupid,
recoverable situation. The latter goes with the remainder of the Unix
rope and may even be instructive if not constructive.
