The WebARonARKit repo is simply a tiny little iOS app that make a WKWebView, hooks up a few message handlers, fires up ARKit, and sends messages back and forth, by the book.

But the WebARonARCore repo is a whole freaking clone of the entire Chrome browser!

Isn't there a much simpler way to extend an off-the-shelf Chrome component like they did with WKWebView on iOS, without rebuilding the entire honking browser?

I know there is a WebView chrome component for Android -- why didn't they simply use that, the same way as they did with WKWebView on iOS? Performance? Does it require features the WebView Chrome component doesn't support?
