More to the point, it was suddenly dropped in as the primary environment, not introduced as an option. This says something too.

It's not rotten through yet (for one, no snide shits in support yet, like it was in Mozilla, those who sit on bug reports are cool people), but you see what the management is, and fish rots from the head down, so... matter of time.
