I agree. Our local shelter is a no-kill shelter run by animal fanatics, and they don't adopt out feral cats. If they got one, they'd probably put it down. I don't see any policy on their website, but I've visited their cat room many times and never saw a feral cat. I used to volunteer there, and on the tour we passed a cage with a feral cat in it. This was a long time ago, so I can't remember what they said they'd do with it, but they did say it wouldn't be adopted. I don't know if they have a spay and release program.
