That's two things:

1. Add a new m-line, but allow it to be accepted and unbundled.
2. Change the transport parameters of the existing bundle, but permit
the change to be rejected.

I would be perfectly happy to require that this take two rounds of
offer/answer to perform.

I understand how that might be useful in theory, but I don't think
that you can make this change without accepting a lot of additional
complexity in the rest of the solution.  I liked the constraint
because it simplifies the rules around creation and acceptance
significantly.  Remove that constraint and I don't know where we are
any more.
