It has not. There are no tools for the web approaching even a Delphi RAD or a Qt Creator ca 2001.
CSS layouts are a joke, and trying to create anything as complex as a modern app with CSS is a road of blood and tears (go ahead and use CSS to implement something like Sencha. Hell, start with any constrained layout available for most native frameworks and toolsets out of the box).
By "most native APIs" you mean a very small subset deemed more-or-less safe to execute in the browser (you won't ever have full access to, let's say, UIKit, or AVFoundation).
And even if animation is rendered on GPU, 1) if you have a lot of them, the browser will struggle, and 2) web animations are extremely limited, primitive, and extremely constrained by layout. Good luck not running into reflow issues for animations which are a breeze on the native platforms. And good luck working around these issues using only animations which won't trigger them.

There are people who build OSes using only assembly. It doesn't mean that tools or capabilities of assembly are anywhere near available for other tech.
