Meta: it's one thing to talk about things some people consider inconsequential. It is another to sidetrack that discussion to be about whether it is inconsequential or not.
Just saying.
There aren't too many CDRs. It doesn't matter if they aren't earth shaking or if they're something that can live in libraries. Let's have some more. Sturgeon's Law applies to everything, even Lisp.

(Though if I had to vote on "what sort of CDR should Pascal Costanza write", I would vote on something CLOS or MOP related... :))
