1) people stop inexplicably calling it "dead"
Being "dead" has its fringe benefits, at least, like no one proposing changes for the sake of change - it gets to be happily frozen and useful with no one trying to e.g. update it from the XML-everything mania of its time (embarassing in hindsight) to the JSON-everything mania of our time (I'm worried there won't even be a hindsight for it to be embarassing in).
Well, except when people propose to replace it with something else because it's "dead" (sorry, I have no interest in following anyone on activitypub - if I want updates from your blog, I will poll the RSS feed you have kindly provided).
