The web is an ecosystem, browsers are species. They create new mutations in a new attempt to thrive. The definition for what it means to thrive is always the same. To replicate oneself the most. That means the largest user adoption. If performance is what users judge by, then browsers will adopt to it. If transitions are what users what, than browsers will adopt. IE had trouble adopting, it had the wrong balance of features. That's why it started to go extinct. You can't DESIGN an ecosystem. You can't tell an ecosystem to stop churning. It just keeps going. Timing also matters. If a fish evolves a hand, does that make a better fish? Maybe not, but if the fish starts breathing, and living out of water... maybe those hands would be pretty useful.
