We're just whittling down to a smaller and smaller subset of users. 99.9% of users shouldn't be made to go without just because 0.1% of users can't have it.

Though even then, ffmpeg is open source and decodes hevc just fine. I get why browser vendors would not want to bundle ffmpeg, but that shouldn't stop them from leveraging it if the user already has it installed.
