Well, I think he sets up a false argument.  His issues can be addressed:

1. if they vary because they intended to implement the same thing, and failed, those are known as bugs and should be filed against the browsers.  Anyway, authors know that they are using an experimental feature, and that implementations might not be perfect.

2. if the spec. changes significantly, then the experimental shared prefix also needs to change, obviously.

No opposition to that. But that's not where we are.
