I too have never seen a long name on a map (and I have seen a lot of
maps) except sometimes on a loopback subnet in V5. Yes, a missing
reverse lookup will causes problems, but they are usually worse problems
than a missing label, so I always address that thoroughly right up front.
If the DNS cannot provide two-way lookup, I say ditch the DNS. At current
maintenance levels I have seen very good updates to the map after updating
name resolution (mostly /etc/hosts in my case). I still see a few of those
deals where the Selection Name stays the address, but the IP Hostname
and the label are names. I either delete and rediscover them, or use
the context menu edit to switch the Selection Name to the name name.
Actually when the name comes along later I prefer to rediscover. This is
because if you don't, the Selection Name of the interfaces no longer
matches the Selection Name of the node. That match can come in handy.

My two cents...

Just to be difficult, I always get the short name, and most of our devices
have forward and reverse lookups in DNS.

What P's me off is that the label doesn't get updated if the reverse entry
wasn't in DNS, but was later.  In that scenario, the object name gets
changed to the FQDN but the map label stays as the IP address.

Leslie Clark seems to think this is normal though. (Am I correct??)

I think this is just a question of how you resolve your names.  If my
devices have reverse DNS entries, then they get the FQDN in the Netview
map.
If not, they will get a shorter name, probably based on how the device is
configured, or sometimes no name at all, just an IP address.
