My concern is because, overall, Google has a bad track record in this area: FileSystem is still enabled, WebSQL is still enabled, PNaCl is still enabled edit: and H.264 was never removed despite announcing the intent to do so.
Eh? What is the spec competitor to PNaCl? asm.js is a cute trick but it still lacks threads which is easily one of the biggest features of PNaCl. So what actual viable alternatives are there to PNaCl?
Of course, not having a good alternative might mean that the other parties in the standards process should take another look at it. But again, that's a totally separate issue from whether it is ok to just ignore the standards process and ship whatever you want, which is what Google is doing here.
