It was discussed at Pgcon as a result of Oleg and Teodor's talk, and at 
the Unconference.

But in any case it's moot here. None of what I'm suggesting has anything 
to do with the storage representation of JSON, only with how we process 
it in whatever form. And none of it will break backwards compatibility 
at all.

So, please, let's concentrate on the problem that's actually at hand.
