Not to mention all the common platforms out there that assume one-to-one.
For example the gethostbyaddr socket library function in both UNIX and
Windows.
If the ordering of records is not reliable either, this means that a
gethostbyaddr result is non-deterministic (unless coded to fail) if you have
multiple PTR records. Ouch.

An IP can have multiple PTR records - there's nothing wrong with this.
However, this can confuse some already existing anti-spam measures that
rely (good or bad) on a one to one match.
