I think you're missing the point. Firefox & IE are browsers, WebKit is a browser engine, market share has nothing to do with WebKit. Chrome gained market share because instead of reinventing the browser engine, they improved on it and re-branded it. John's point seems to be that IE & Mozilla using WebKit wouldn't result in a mono-culture because they could still produce their own features and not worry about reinventing the engine.

That assumes that the WebKit engine is already as good as we'll need it to be or can be improved as needed in arbitrary ways.

But it's not, and it can't be.

Think about how something like the Servo project would happen (or not) in a WebKit monoculture world.
