IMO this whole VDOM debate is big distraction, once you solve DOM perf you hit the layout performance wall. We need to improve that instead

Seems like Google is all geared up for JavaScript performance and not at all for layout performance, even though layout hits us harder

Ok, but as my blog post notes, we can get detailed traces of JS execution but nothing for layout. Or am I missing a devtools feature?
