What exactly the reasons are and why would we want to implement that? Pardon me, but going by the previous history, "The Austin Group Says It's Good" is more of a source of concern regarding the merits, general sanity and, most of all, good taste of a proposal. I'm not saying that it's automatically bad, but you'll have to go much deeper into the rationale of that change before your proposal is taken seriously.
