The problem is that the web standards have now grown so much that it is impossible to write a complete new web browser from scratch. Firefox is not coming back, because Mozilla seems to prioritize other things than code quality and the actual usability of their software.
And yes, I know that the SerenityOS developers are trying to do it, but while some very advanced things work "good enough" in their browser so that Twitter and Discord's web client works to some extent, the more basic things are so broken that their browser cannot even render basic HTML 3.2 sites properly.
Google's end goal is probably to "deprecate" HTTP 1.x and force everyone into using their own replacement for the protocol. Their protocol is going to be like the thing they call "HTTP2", an insanely complex protocol that is impossible to implement by a small developer team. In the end their own protocol becomes a "rolling release" protocol that only works with Google's own app, at which point they can completely stop releasing RFCs for it.
