In general too, it would be cool if there was a feature to reverse a merit within 10 mins of sending it.
If there is no reverse for bitcoin transactions, there is no good reasons to have any reverse for merit transactions, IMO. I don't think forum needs merit congestion. Meriters simply take care of each time they decide to send merits, typing amount of merits intend to send, check it again, before clicking Send. It's fine.
