> Only reject a "best practice" if you understand why it was there in the first place. I'd agree with and extend your remarks, if you can clearly document why you're creating your own best practice, then its OK. Or rephrased in a negative sense, If you can't clearly write and permanently document an explanation, then you probably don't have a good reason.
