The FAI cares about historical accuracy to the degree that people care about resurrecting accurate versions of dead family/friends/ancestors, where accuracy is subjective and relative to memories and beliefs.

Oh, boy, that's such a can of worms. Let's resurrect grandpa, except we'll delete some features of him that we don't like and try to forget about. Or let's resurrect my girlfriend from college but let's make her a nympho.

I would venture a guess that people rarely care about accurate versions of dead people, they would prefer improved ones.

All in all, this just looks like a silicon version of ancestor worship. If you venerate your ancestors or, say, if you are a Mormon you convert them the Mormonism, isn't that acausal trade in practice? They begat you, you do things for their souls...
