When you cut a headspider out of a victim, the headspider should pop back out

That just creates a lot of tedium to the point where it'd be more efficient to just debrain and clone the person/soon-to-be ling giving a 100% chance of the ling not taking over, rather than bothering with the chest surgery at all, which is already a crap-shoot anyways due to RNG.
On top of Changelings having enough durability and extra-lives as is imo.

I don't think it creates any tedium. It basically adds an additional fight the tediousness of the surgery which previously is just boring if you know what you're doing. I've never heard anyone say that changeling surgery is a crap shoot. It works all the time, but it can take a few tries. I'd say that debraining and cloning is a more dangerous option because if the headspider has already taken over by the time they die, then you're cloning a changeling. Plus, I've never been a fan of considering murder-then-cloning a medical procedure to cure problems.
