Well, with you edit now you are agreeing with me, so I can't even tell what your position is. That is what I meant by throwing a wrench into everything.
My position is what Matt just said:
As much as I hate to admit it, because I think it will hinder forward progress of the site in the short term, I think that Bob and Scott both have a valid point here. Previously there was no policy for adopted pages. It would be unfair to retroactively impose such a policy on adopted pages. People should be given fair warning before having to give up pages they've adopted. We can implement the new policy, starting today, and move forward with it in place. But applying it retroactively doesn't seem like a good idea.
Also, I did state a solution:
Just make it a rule that everyone knows about. Perhaps in the adoption forum that was proposed. I think it would help to come up with and let everyone know of some rules for adopting a page.
I do propose solutions; you just choose to ignore them. This one seems a simple fix.
