First.. great photos to explain the issue! A great example for others to emulate!

Second, I've seen the same issue on one of my bikes. I don't have troubles with the derailleur hitting the spokes, though.
I've used the Park DAG tool (derailleur alignment gauge?) to confirm that the hangar wasn't at fault.
I haven't followed up on it, but I don't expect that it is due to bending. I'm more inclined to blame wear at the upper and lower pivots. This is just speculation, though.
The upper pivot doesn't move very often, so I'm less inclined to blame it.
The lower pivot moves a lot, and doesn't really have a good way to preserve the lube , nor a good way to add lube periodically. You have to pull that lower pivot all apart, and that's a big pain.

I did retire the Cyclone GT that's been on the bike for a while, mostly because the parallelogram spring was getting weak. I've got a Cyclone GT Mk II on it now, and the pulley cage is much more aligned.
Ideally, I'd pull out that old Cyclone GT and try to quantify the play in that lower pivot. However... other tasks have higher priorities right now.
