That's insanely obtuse and bureaucratic response and has likely been designed as such. I mean, to claim that because _some_ domains can get unregistered, abruptly removing a whole class of domains "does not impact the life cycle of the domain" is entirely nonsensical. It's like saying because computers, being physical entities, may sometimes break, and all of them will break in finite time, it's entirely fine if all your computers shut down immediately and it has no impact on anything. This just sounds as "we don't care and you can't do anything about it, suck it up, peasant".
