The real issue is that Asterisk needs to be able to understand all of those
messages and transmit them across a channel bridge in the form of a
control frame.  This isn't as big of a deal with the two messages that you've
suggested as it is with vendor proprietary extensions.  If we don't know what
the messages say, we can't correctly interpret them in a protocol agnostic
way.  But those two messages could certainly be done; they just haven't been
(yet).
