So the 'to' talks about the identity of the backend server, the 'from'
talks about the identity that is discovered. The 'to' SHOULD be included
in the first response (and not thereafter) the 'from' MAY be included in

If there is an 'identity that is discovered' and what form it has, can
vary from payload to payload. So the 'from' MAY contain a full JID when
you use XMPP with BOSH. The 'to' SHOULD contain a server identity,
whatever payload you use BOSH for.
If I use BOSH for example for an home brew communication protocol, then
I may do whatever I want with the identity that is in the 'from'. That
was one of the use cases for splitting up BOSH to XEP-0124 and XEP-0206.
