Yep. Consider the following situation:
user at example.com is subscribed to anotheruser at example.net (state=both).

anotheruser at example.net 'moves' his account to example.org, using
something like JRU to port his roster and 'deletes' his old account.

user at example.com sends a presence to anotheruser at example.net and gets
a <gone/> error (because example.net has only marked this account as
deleted but still retains the account data for some amount of time)
with the new JID inside the redirect.

Should the example.com server subscribe the user to the presence of the
new JID automatically? Account transition could be made more-or-less
transparent that way... (though the user at example.com should of
course be notified that this has happened.
