Mozilla has a massive platform for collecting and analyzing user/software feedback. I'd imagine they've got good metrics on web-breaking moves. Chrome, from my experience, relies on bug reports on their issues site; Microsoft and Apple go slow and keep things opaque/in-house. WHATWG watches, suggests and makes changes based on the eventual consensus.

As for html5 Canvas; other than the accessibility issues addressed in the past two years, I wouldn't say it's broken. We're now looking at a new version of it. I think it was called version 5 by Hixie.

I wanted vendors to solidify consensus on a version close to what currently exists, with minor changes for accessibility. The WHATWG and W3C have chosen instead to make broad changes, as proposed in version 5/the Hixie-Atkins draft.

So, it's on the table. As always, browser vendors will decide on the actual direction.

I'm still for making a snapshot with createPath and an opaque CanvasPath, and saving version 5 for the more distant 3-year future and HTML6. The W3C and WHATWG have gone ahead with version 5, with support from an Apple employee.
