SIP has been here since 1999, telecommunications also adopted it, lots of stable software, smooth cooperation, lots of suppliers.
Some thought that by introducing a new protocol they could generate better business/profit. I see no other advantage in Matrix.
There's nothing important in Matrix that can't be done in SIP, and there's nothing in Matrix that's much more deserving of a new protocol. There are many standard extensions for SIP, and if you're still missing something, it's easy to add.
