If the console attached fbcon, then I agree that console should decide when to detach fbcon. But that's not what happens, it's fbcon that attaches itself.
It's not that you're wrong, it's just how the current vt/console layer works. If someone do decide to add this feature to the vt/console layer, then I'm more than willing to have fbcon support that as well.
