Sure, of course, but unless funding is coming from users the economics won't change, because:

The vendors cite an aspect of said responsibility (security!) to get rid of an other aspect (costly maintenance of a low-revenue feature).

The web is evolving, there's a ton of things that developers (and website product people, and end-users) want. Of course it comes with a lot of "frivolous" innovation, but that's part of finding the right abstractions/APIs.

(And just to make it clear, I think it's terrible for the web and vendors that ~100% of the funding comes from a shady oligopoly that makes money by selling users - but IMHO this doesn't invalidate the aforementioned resource allocation trade off.)
