Awesome to finally have nesting. The way I see it, this took 10 years longer than it should have.
I feel the only big thing missing from the vanilla stack for me right now is a template element that multiple html files can share. Just like how you make a blog header in Jekyll or Hugo and it adds it on all your blog posts get the header. I haven't found an easy way of doing that if I have a bunch of html pages.
That's what an iframe is? I guess there could be a partial element that works like <partial href="header.html" /> but if it's referencing HTML, what about JavaScript or CSS it includes? That's exactly what iframe handles.
We had it briefly in the form of HTML imports, but the powers that be removed it because it’s not powerful enough for JavaScript/web apps development; totally ignoring the fact that the web isn’t just about apps.
