v1: https://lore.kernel.org/all/878cd6bcbbe2d5677d2f63da13294c148268552c.1782927917.git.robin.murphy@arm.com/ Per the discussion on v1, the aim here is just to make things safe and functionally correct for now, and now with a command-line option for distro users to get themselves out of a corner if they really need to, I think that's reasonable enough for HAFT being a very new feature. Thanks, Robin.
