I completely agree we need to improve the reporting around framerates. I've been thinking about this in the context of the proposed "Display Paint Notifications" specification. If the web application receives a callback when the painting needs to occur instead of arbitrarily based on timers, then the web application can accurately keep track of framerate while also having the ability to scale down the framerate as needed to provide a great experience even on lower end hardware. I prefer the callback approach over a reporting API since it puts the web developer in control over the framerates and experience.

I'd like to see some metrics reported about frame rates.
