That proposed video[loading=lazy] addition is nicely formatted at this handy preview URL for anyone interested in following along whatpr.org/html/11980/m...

as the issue tracker note says, we're looking at browser patches and tests too. Fun to be back tinkering in standards again, and I think this will be a nice addition for performance.

Oh nice, I like that.

looking forward to what you put together. This is such an under-invested area of tooling and even without any standards for DCE, there's so much that can be done.
In my opinion, enhance.dev came closer than anything I've seen to nailing the server conventions companion that web components need.

Yes! When I first learned about web components, the "is" attribute made the most sense for how I'd use them most of the time. I still think that, but because Webkit won't implement it, I've gotten used to workarounds. Custom attributes seem as good as "is" (and maybe better?). Would love to see it.
