>A single browser codebase hurts the maintainability of the Web platform. To the extent Chromium has a monopoly, Chromium bugs are the standard and sites will depend on them. Yes, this is already true to some extent, but it could get much worse. So fixing bugs would get harder. Your last line doesn't follow from the rest of the paragraph. One platform is easier to fix than 4. And it makes it much easier to develop for. Either your site works on Chromium or it doesn't work. You don't get into a situation where it works for 80% of your users. >Say you want to rewrite the Chromium style system for parallelism with Rust, like Mozilla did with Firefox, and Google says no? I'd be concerned about that if Chromium hasn't been eating everyone's lunch for nearly a decade now. In terms of rendering/js engine they're clearly ahead of everyone else. For all of Mozillas efforts they still haven't matched chromium let alone surpass it.
