This doesn't need to be hypothetical. We can look at that trade directly. We traded hardware fingerprints that aren't trackable across services for DRM in HTML. That's what we got.
So glad they got in on the ground floor instead of continuing to work to never have it enter the spec at all.
DRM is in HTML. That happened already. Mozilla refusing to implement it is not especially likely to make W3C change their minds. It might slow down the rate of adoption among content providers, but it's not gonna change the spec.
I hope we get more from Mozilla than hardware fingerprints that aren't trackable across services. I hope we get a lot more.
