Prevent cluttering up the rtpsession, and keeping things localized. Also write TWCC-seqnums for *all* streams in the session if configured by caps. A while back WebRTC was not doing TWCC for audio, basically breaking the whole idea of a "transport-wide seqnuencenumber" applying for all bundled streams. However, they have since fixed this, and now it no longers makes sense to be able to single out certain payloadtypes for use with TWCC, rather just including them all. This also makes using RTX, RED, FEC etc much simpler, as it will apply to them all as they enter the rtpsession.
