And this is kind of a huge deal. 3 different implementations rather than 2 is kind of like the old saying "never go to sea with two chronometers, take one or three".

I'm not saying Blink exactly matched WebKit anymore, before your re-architecture. But it shared a lot.

If you have a difference in behavior between 2 implementations, then it's easy to see think of it as saying one or the other is right. And which one is right will be partly influenced by the amount of exposure the feature has had, multiplied by market share. Which is not a great criterion to use if you want a spec that hangs together, especially if a reimagining like Servo is going to come along and rub against the grain of every arbitrary decision ever made.
