The use cases I've heard about revolve around presence-enabling email 
programs and contact books and such. So for example your instance of 
Thunderbird could show a little presence icon next to mail from 
stpeter at jabber.org if I advertise a TXT record with that address. But I 
could have multiple email addresses so you might want to presence-enable 
them all.

Naturally, there is absolutely no control over what people can publish 
in their TXT records, so this kind of information is easily poisoned 
(I'll add a security consideration about that to the next version of the 
spec). But that's true whether you advertise one email address / JID or 
more than one.
