It's not ruled out. Read my previous posts, I quoted the sticky twice and the OP clearly separated it from the ruled out idea. As for your point about GC: exactly.
So far, everyone who's posted negatively has:
(a) Thought it's ruled out, which it is not, or
(b) Found it unnecessary, but as I've pointed out, it's not as easy to tell as is as they say it is. Collectors only show a day or two max, and league/attacks won/defenses won/troops donated/troops received often aren't helpful for weeks.
I think this idea would really help a lot of leaders, and it isn't ruled out.
