Hi,

If older platforms had working implementations, it could always be added 
back in. Meaning, there should be plenty of mature implementation out in 
the wild.

I don't think that's for the specification to say. Let the developer 
decide which is better. I provided plenty of examples where a 
lower-resolution H.261 feed is preferable to audio-only (e.g. video 
games). The specification should give developers the option to choose.

Furthermore, I'll repeat again, we're not choosing between H.264 and 
H.261. We're choosing between H.261 and no video, for only the 5-10% of 
calls where there is no agreement on a higher-end codec (VP8 or H.264).

Again, this is up to the developers to choose. I don't necessarily need 
a high-resolution video for gaming.
