I'm not sure how disruptive that action would be. Yes, that is becoming very much tempting at this point, isn't it? In any case, I've pushed out 'seen' with the "these extensions that used to be honored in v0 won't interfere with repository upgrade" patch I sent earlier, and I am hoping that it would be a reasonable middle ground that won't regress things for users while making sure we do not honor random future extensions by mistake.
