If you with "constituent RTP session within it" where it is a bundle
means the RTP media streams resulting from that particular SDP media
description (m= block) then I believe I agree with 1).

When it comes to 2) what makes this different from rejecting each m=
block within the bundle?

3) is required if legacy fallback at all going to be available.
