Heya Nikhil, Thank you for raising this KIP!
Your proposal makes sense to me. In essence you are saying that the permission required by WriteTxnMarkers should be the same as for CreateAcls and DeleteAcls, which is reasonable. If we trust an administrator to assign the correct permissions then we should also trust them to be able to abort a hanging transaction. I would support this KIP if it is put to the vote unless there are other suggestions for improvements!
