Bob, I don't see how it encourages anything. It's just a smidgen more info in a couple of places that would take maybe a few lines of code to implement.
As far as the creator email put in the approval message, that would reduce the chance of someone getting confused. That's only 1 line of code:
this.approval.body += "\r\nGroup created by " + this.account.email + "."; (or something similar)
