Yes.

No.

First and foremost, its not backwards compatible. Remember, SIP is already
an RFC. It is not open season for "change SIP in all kinds of new ways". We
are working to (1) fix bugs in the  spec, (2) clarify things that are vague,
(3) describe cases not already covered in the spec. If something is clearly
defined and working correctly, I do not believe modifying it can be
justified.
