In the ASN.1 thread my point was that we should know well what came before before we replace it. Sometimes the old wheel has nothing worth saving other than the idea of it, and when the pain of using that old wheel gets bad enough, we must re-invent it. Doing it ahead of time is risky and has opportunity costs such that the new wheel needs to be that much better than the old to be worth pursuing early -- it's an economic analysis problem. > > Well maybe we should do that more often.
