You missed the point. Your position is that there should be only one browser engine. But you're trying to use two browser engines, which are very different, to support your argument.
No, you missed the points. My major point was that we have the source code and nothing changes that. My second point was that I would rather all browser engines work the same and if they can’t then I’d rather just have one popular browser engine.
So I guess it is great, isn't it?
