Right. All this treating the DOM with kid gloves seems to be due to its pre-existing weaknesses. Why not just fix those?

Browser vendors have spent the past several decades trying to fix those weaknesses and haven't, it seems like a very strong indication that it is not exactly an easy thing to do.

This might be just because most web apps never had a bottleneck on JS->DOM changes.

This is blatantly false, as the DOM has always been a bottleneck for web apps.

Because you can't "just" fix them. It's a complex problem with no easy solutions. Don't you think it'd already be "fixed" if it was easy?
