I also want to reiterate that having a MTI codec means Mandatory To
Implement.

That means, that should we decide to go down the H.264 path, Firefox and
others will be forced to support this Rube Goldberg machine for obtaining
H.264 for an indeterminate amount of time, long after WebRTC has moved on
to prefer other codecs.
