We do recommend it:

The identifier that Rowland is worried about in terms of replication
behaviour is actually the invocationID, and we do not re-use that.
This is actually a problem if this kind of re-join is done
often/automated, as objects in AD keep a list of every DC that every
existed on them!
But for practical, humans scale operations it is fine. We delete all
the other objects involved (server objects, DC objects etc). If
something isn't being cleaned up then that's a bug, a rejoin with the
same name is normal in Samba.
I trust this clarifies things,
