But is it necessary? DO you ever move URBs between anchors?
I don't think it's relevant what I would or wouldn't do. The question is
if someone out there would do that. Without any guidelines saying it's
explicitly disallowed, some will do it. Actually, even if there are such
guidelines.

It would be, if the deal is necessary. In hindsight it still looks
to me like completion should unanchor an URB.
Once again, I'm not sure that matters so much anymore. The anchor API
has been around for a while, and there are drivers using it. Adding
another API will undoubtedly create some confusion. That's why I think
that the question should be what is functionally flawed with the current
API, and if that can be fixed.
