The argument is essentially: "It took up lots of engineering time and effort to maintain compatibility with other platforms, so this allows us not to worry about other platforms and only focus on our own and that will allow us to move faster." Hopefully this is easier for everyone. If the chrome multithreading architecture really was the pain point then does that mean that webkit will also be deleting thousands of files and become easier to build, just as the chrome team is removing compatibility for other webkit targets? Or will WebKit remain the mess it is now because it strives to work on all the other platforms? What if Apple decided to do the same thing? WebKit is this wonderful open source success story in part because it runs in so many places on so many things, but isn't a large part of that only enabled because the main contributors took the time to make sure that their work continued to run on the various different architectures? Will Google turn away patches that enable Blink to be compatible with platforms not their own? This is an interesting move.
