Proposal to add efficient DOM diffing to browser

I'm curious why this hasn't made it to the browser yet and doesn't seem to be explored very seriously? So many web-frameworks revolve around trying to address this issue, why not get rid of the overhead or at least reduce it?

  Diffing the DOM without virtual DOM

If by faster you mean faster than React I think there is evidence it can be. The author of the issue writes lots of dom utility and rendering libraries and I believe domdiff is more or less what he describes in the post:

https://github.com/WebReflection/domdiff

You can find it placed way above React in the usual JS rendering benchmarks:

https://rawgit.com/krausest/js-framework-benchmark/master/we...

Now it's not entirely clear whether these benchmarks convey something meaningful except for maybe the point that most frameworks are quite fast. That being said I think it's developer experience that really stands to improve. Thinking of view as a pure function of state was a great innovation, but existing implementations can end up fracturing the view into virtual doms and non-virtual. Then you end up with problems like D3 and React not coexisting.

I feel like I heard something from the lit-html folks that a long term aspiration was to integrate some learnings from the project into chrome, but I haven't been able to find where again.

There has been a trend in JS with libraries becoming idiomatic to the language to later have the issues they targeted be addressed natively (a la JQuery).

In general, I definitely appreciate your point about adding complexity to the platform, but I think when it comes to web technologies that ship has long sailed. I really see it as an opportunity to bring a lot of simplicity, chiefly filling that void that's birthed a billion JS frameworks.

Thanks for the thoughtful comment.
