I'm reading Alan's post as saying that he has a competing implementation.

But I believe that both approaches Alan offers are overkill: he
proposes something like the db-API, where there are multiple
implementations of the same API (except in the case of the db-API they
aren't necessarily 100% interchangeable). It'm sorry for Alan, but I'd
much rather pick one implementation (simplejson), fix 1-2 minor issues
with it, and put it into the standard library. Anything else is just a
lot of opportunity for endless debate without much benefit.
