This idea is brand new so far as I know. It was suggested by Sexpower #7802 in discord. The idea is to add reverse stealing to the thief skill abilities either through aspect as suggested by Blaise or just through membership in the Thieves Guild once it is hashed out and becomes active. The specifics behind the idea are simply as a way to add an item to someone's pack that you are snooping, either as a joke with a note, or as something more sinister with a trapped chest or box. The idea is simply meant as a fun additive to thieving and might curtail some taking in favor of joke making. I also has the thought that there could be a stone or rune that was able to be enchanted to cause one item to be returned to you if you were targeted by a thief, and maybe for fun it would take one of the thief's items with it. You would of course have to have it re-enchanted each time afterwards, maybe a limit on how often you could recharge it would prevent abuse by locking thieves out altogether. If you like the idea post here so we can let the bosses know.
