IMO it's fine from the protocol point of view to put TXT records in the
reverse DNS. (Remember to allow for following CNAMEs and other forms of
classless delegation.)

From the operational point of view, you're going to bump into a lot of
annoying road blocks: undelegated reverse DNS, provisioning systems that
only allow for PTR, etc.
