That's not to say that cybernetics cannot exist side by side as replacements/alternatives to cloned replacements, and cost and time of one versus the other can vary by setting. And it's not necessarily to say that cloned replacement limbs are a Sindome concept (though the proliferation and commonality of other vat-grown products sets the stage for it to be and hints at the possibility), but to say that such replacements do not fit in a cyberpunk theme ignores a fair bit of the cyberpunk genre.
But VS and clinics have historically had offerings for organic replacement parts. I think prior to the intro of the sever system, but this still sits around in IC Lore.
Anyways, for Sindome, I don't see cloned replacement limbs being a thing. The rich have fancy cyberware, not cloned limbs.
Reattaching severed limbs is something you should investigate in game.
