The question is who is doing the shooting and whose foot is being shot.

In this case, you've got a situation where the IETF and the end users
have managed to shoot the ability to deploy NAT444 in the foot.

If we set aside this /10, that restores the ability for the ISPs to deploy
NAT444 (bullet removal). Now, if an end-user proceeds to use this
space, then they have shot off their own foot and I doubt anyone will
have much sympathy for them. In other words, they can only harm
themselves, not their ISP, not the rest of the community, so, who cares?

This isn't about people who shot themselves in the foot. This is about
people who are loosing feet from shots fired by other people.
