Most of the browser vendors care about standards groups and are highly influenced by what they say. Certainly that's true for WebKit-based browsers, where I have some first-hand knowledge. One dysfunction in this case is that the <picture> proposal was developed in a splinter group that didn't include browser vendor representatives and thus was somewhat disconnected from the larger conversation. I will also add that both browser vendors and standards groups care more about people's use cases than their concrete syntax ideas, and ideally people making proposals should learn to think that way as well.
