No, I don't agree:

1) Mangling the SDP is not the way to go (and theoretically will be prohibited).

2) Even if allowed, having to mangle the SDP and perform a fake SDP
O/A local renegotiation is not cool at all. Note that, in my use case
above, the bitrate limit is decided by the server at any time).

3) It does not work in PlanB if I send two video tracks because b= is
per media (and not per "ssrc").
