Understood, but with everything moving towards the web now a days and compatibility between browsers being such a hot topic, why not throw away the code and standardize on another existing, standards complaint platform? Any number of companies have dropped huge chunks of existing code base, Apple and Google included. The IE team could work on Webkit just the same as they work on Trident. And don't get me wrong - IE has been better since 10 - cross browser testing has gotten easier in recent years, but it still needs to happen where if something works / looks good in Chrome, Safari just generally needs a quick pass to make sure it's the same with very minor tweaks here and there.
