(IPv4 hat on)
I've taught my staff to plan using the reverse zone file. One can easily
see which addresses have been used and which are free (sort the zone
numerically!). Far more useful than putting names and addresses into a
spreadsheet... which I suspect.. never mind...

Having a correctly configured (ie complete) reverse is very useful. Mail
and other services use the information. If you just have an IP address,
a 'dig -x IP' will give a human understandable name. Can't think of any
sane reason not to properly configure the reverse zone..
