I dislike the idea of a character dying on extended and then never seeing them again because they accidentally walked out an airlock when they shouldn't have. Or hivebots happened. Or spiders spawned baby spiders in their stomachs. Please keep it in the lore or something or yes, add more drugs to bring people back if other methods don't work.
I also feel like psychologists are going to have even less of a role. They'll be there to talk to for those who already have issues but ah, what else now?
