Well, it is pretty invasive, and I'm not sure anyone has bought in on the
design.  The problem I've got with it is that it's a one-off that embeds
a whole lot of new parser/planner/executor infrastructure to serve exactly
one datatype, ie jsonb.  That does not seem like a good design approach,
nor in keeping with the way Postgres usually goes at things.

If the patch were proposing a similar amount of new infrastructure to
support some datatype-extensible concept of subscripting, I'd be much
happier about it.

I believe there's been some handwaving in the past about extensible
approaches to subscripting, though I haven't got time to troll the
archives for it right now.
