Lore-wise, Vagrants never wanted any symbiosis or coexistence with humans. Their approach is slightly different and indirect as they are far less numerous than the Omicron Nomads, but their goals are the same.
Good squiddies coexisting with humanity were always player RP, and it was never part of the canon lore.
It depends on how you do it, if the poor fellow's basically coerced into doing what the squid wants it's still extremely one-sided and I always assumed this was kind of the rule. There's no coexistence or symbiosis or good vibes with the individual there, it's still pure domination and brute force and I'm not opposed to that. But a lot of character development is being spoiled considering that many people wrote their characters in such a way as to still have some hint of the old person, just horribly warped on a personal and spiritual level. There's none of that if it's just a bodysuit.
