It's kind of a "everybody sucks" situation and there's no real winners.

Archive.[whatever] setup a server system to give you access from a country not your own, so that abusers have a harder time of archiving illegal content, then instantly reporting it to get the entire archive taken down. He uses EDNS to do this, but CF doesn't provide EDNS since it's a privacy issue to them.

So archive.[whatever] doesn't work for CF DNS because he doesn't want to risk bad actors being able to take down the archive.

Sensible reasons on both sides, especially for a service like archive.[whatever], and the real losers in this situation are the users.
