Can you defend the proposition that Firefox isn't a viable browser for lack of these APIs by listing popular websites that won't work without them?
Serious question, because I can't think of any.

The pixel repair site is an interesting example, but AFAIK, Pixel phones have about 2% of the US market share and this website is only useful to a small number of those users (those who encounter a serious error) and isn't something even those users would be using often. If I had to use this website and couldn't get my phone fixed another way, I could install and use Chrome (or I presume another Chromium browser) and use it for this single purpose. It would take me only a few minutes/hours(?) and then I'd be done with it. Why would a site like this keep me using Chrome permanently? I just can't imagine that.
Not being compatible with those sites is definitely not the barrier to widespread adoption of Firefox.
