Given domain A and B I wonder if it's a problem if when a request is done from A, B can feed information back to A (through the URL; http://domain-a.org/?data=data) without any sort of access check being done anywhere.

Yeah, I've been thinking about this scenario too. I think I agree with you actually, especially given that I don't see any good usecases for not doing the check in this scenario.

Agree? I was just wondering :-) In any case, I could easily solve this in the specification by having a "has been non same-origin flag" which is set to "true" the moment you make a non same-origin request or you are redirected to a non-same origin location. Based on the value of that flag you would then decide to do an access check. Sounds reasonable? (Besides of course the already in place algorithms for a non-GET request to a same-origin server which redirects to a non same-origin server.)

Yes, this sounds good.
