I can confirm that there are currently mobile phones on the market, that do have this type of restrictions, i.e. they in general support certain audio and certain video codecs with certain modes, but not all combinations of them, due to limited HW. And these are phones that do have SIP VoIP/video clients, so in that sense they are relevant. So if we want to take RTC-Web to as low end as SIP has already gone, the issue is probably real. At the moment these devices don't typically have a browser with all bells and whistles, though.
