track the things I mentioned in the mail to Tab, I think.

Other things we're a bit concerned about:

and not sure whether we have bugs tracking these:

Plus of course the cat/hat stuff this thread started with.

For those of us not intimately involved with Blink development, what 
does this mean in practice?

The canonical way such things have worked in the past is that a UA ships 
something and then claims it can't change it anymore because it has been 
shipped and changes would break compat.  For some values of "worked", of 
course.  ;)

That depends on whether the implementation is willing to adjust as the 
spec changes.  Historically UAs have not been terribly willing to do so, 
though some have been more willing than others.

Without breaking compat in the process?  Or will Blink be willing to 
make such breaking changes?  That's the part that is least clear, esp. 
considering the original mails in this thread explicitly talked about 
some breaking changes Blink would not be willing to make.

It's not really easy to polyfill the event path, unless I'm missing
