It is true, that the jail-id is the only unique identifier from OS or developer view. But there is
another view, the administrators view: The jail-id is a not predictable number, but the
hostname is in many (most?) cases the unique reference. So it makes sense to be able to
select a jail by it's name.
The rc.conf jail framework also requires unique hostnames for jails, because the jail-ids are
write to /var/run.
So I agree that the man page should contain the warning, that the selection by hostname/ip
address may lead to ambiguities, but this is a very useful feature in daily jail administration.
