We prefixed our pointer events implementation (which, yes, prefixes have issues and we should stop doing this IMO). Blink is talking about unprefixed, on by default. We updated the implementation and only removed prefixes once we could demonstrate consensus with other browsers (Candidate Recommendation, in this case was one signal of that).
Matt and Rossen from our team were at the CSS F2F where this is discussed with some hesitation on design and I'm sure they'll weigh in further on www-style (this API area's not my cup of tea).
A consensus process, while annoying at times and never perfect, makes for a better and more interoperable web.
I realize that I'm an outlier but I support prefixing as a possible solution to this sort of thing; but that's even more out of favor with the CSS WG than what's being proposed (AFAICT).
Looking forward to timely www-style feedback, it's much appreciated.
