The social theory on the proxies is also that they are fully frozen. So
assuming there would be new good features that people want / need from
projects, they'll naturally migrate to newer direct APIs. More carrot
than stick.
Just pulling APIs that work for people is a good way to make people mad
at you. But giving a gentle nudge because we're never adding new
goodness here is fine.
