Personally I'm against the player getting perfect ressurection tech, for both lore and gameplay reasons. In order for it to be relevant in regular gameplay, it shouldn't be some sort of hyper expensive late game tech, because by then you'll prob already have so many fully trained gals that it wouldn't really matter much to keep one gal or another from getting snuffed.
Lore wise, it wouldn't make much sense for the gals, who can't even reproduce optronic computing (as stated in the research text) to perfectly reproduce tech that only the star gods have.
If reincarnation tech is added, it should be much like the other stuff the gals manage to make: dirty, dangerous, and maybe kinda sexy, but far from perfect.
