RE: hit regions

Thanks Benjamin. There's a lot of history here.

Is there a discussion anywhere where pixel based hit regions are elected in place of path based ones?
I couldn't find any email about this apart from one on the WHATWG mailing list.

FYI since I was selected as an editor, I'm trying to get up to speed on the Canvas2d spec. This topic seems to generate most of the email traffic and I want to understand the design decisions.
