Even without the TR-Lock the second play would not be "nothing", would it? A Throned Feast is played as two Feasts, too - no matter it gets trashed inbetween. So BoM would still be played, and only the lock hinders it to be played as BoM again once it's trashed.
You can look at the other thread for the arguments from that time; my position hasn't changed. Throne / Band has a special-case ruling that makes Throne lock in; it's an interpretation of how Throne works. *Without* that ruling Band would do nothing the second time.
I'm not disagreeing with your position, just stating that when I first read it, it made sense to me that Band returned to doing nothing from the Trash as it's no longer in play. (This is that card until it leaves play.) But for purposes of continuity with other one-shot cards working with TR, I have no problem with Band being played under those rules when designated as those cards. (Feast, Embargo, Mining Village, etc)
Unfortunately, even if it weighed the same as a duck, it still could not be... a Witch.
