While a horde of zombies voted you down I quite agree with that point of view.
Even if it's not as black & white Google already attempts a lot of this. They basically want to be the ones to decide.
There's no "consortium" it's just "lets push feat ZZ on our websites, web clients, and say its the new feat everyone has to support. Plus its open source anyway we're the good guys!"
If others disagree well, so far it's been pretty much a grey area. Google keeps pushing the technologies others refused. But when Google controls even more of the market, let's say with 50%+ Chrome (they have the market already, website wise, except for FB.), there won't be a need to push anymore.
It'll be Google's way or, well, nothing. Even if it's features that are released within 48H.
