I think another possible evolutionary reason may be preventing rogue drones.

A rogue drone that can sting repeatedly is a huge risk to a hive since security screening is only enforced at entrance and the rogue one(s) are inside the hive. This way, with the one-shot stingers, the worst possible damage is the loss of another bee, and the problem drone has taken care of itself.

What's your take on that hypothesis?

But as lanrei comments, "When bees sting other insects they can sting them multiple times, like a wasp."

Do you mean rogue "worker bee" rather than "drone"? Drones don't have stingers.
