I'm not saying it's relevant, I'm just interested in your opinion about how such a case should be handled.
My question has nothing to do with policy slots, I am just interested in exploring your position.
The reason I made the example the way it is is simple:
Terracotta Army gives mortal units that don't transfer ownership. It would be possible for these units to change ownership - tag them as being units created by that wonder, then just move whatever is still alive to capital of the conquering player. That's obviously not super-practical, but possible. You seem to be okay with those units not transferring.
The thing I changed is that the unit that is granted by my pseudo-wonder is a "permanent" unit that can't be removed from the game, and I want to understand whether for you that changes something about how the wonder should be handled.
Again, has nothing to do with the policy slots, I think I made my case on that one, you made yours, it's obvious that we won't come to an agreement. I asked purely out of interest, so stop avoiding the question as if I was trying to get a gotcha-moment out of you - whether the wonder itself would be well-designed is irrelevant, it's just a vehicle for the effect.
