Well I think there is a way to define the difference using SRV
records: if there is one we should consider it separate domain (even
if it should point to the same host of the main domain, since they
must be virtual hosts)
No, because "conference.jabber.org" needs SRV records just the same
as any other domain.

No, since all the cases where we may need the concept of subdomain
could be solved at application level with other extensions (e.g. I'm
thinking of a case we worked on time ago where we had to consider a
subdomain trusted and autoaccept all subscribe from that subdomain)
I would argue that there is no such thing as a subdomain, from the
perspective of XMPP.
