see how H.264 fight on VP8. :)

The main benefit that I see would be encouraging Apple to support WebRTC.  But there's still Opus, and Apple has never supported any of the Xiph codecs.  

iOS support in the browser, any browser, without the need for a native app would be a very nice thing at this point.

The lack of developers in this forum clamoring for this H.264 support is noted.

In my opinion, I think there should be a minimum set (aka multiple) of MTI codecs as different codecs would be better supported for differentiating use cases.

In other words, 

MTI for (1) pre-recorded media, (2) live encoded streams (3) screen sharing

For example, H264 may be better at pre-recorded media in terms of quality and bandwidth that is being streamed live.

VP8 may be better for live videoconferencing because it requires less CPU and quality is very high (with respect to bandwidth used in comparison to H264).

and a lossless video codec would be much better than the above two for screen sharing for multiple reasons. 1) no quality degradation (no blurry text when rendering). 2) lower bandwidth (as opposed to lossy motion prediction codec...only pixels that change are transmitted between a configuration full frame interval). 3) again, lower CPU (no intensive algorithms required for prediction, entropy, etc etc).

so, if I were offering a proposal, I'd probably have at least those 3 MTI video codecs.

just my 2c

If it's supposed to convince us H.264 should be MTI, it's not that great, IMHO:

I think this is a great news for us. I am not going to compare between VP8 and h264. 

Many hardware support only H.264 and trans-coding for them(in the gateway) will not be a good idea.
