Yes, it will, but I think that that will create more problems than it
will solve (which is not to suggest that an implicit cast is the right
thing). That will require that any non-trivial usage of jsonb requires
copious casting, where nested hstore does not. The hstore module
hardly contains some nice extras that a minority of jsonb users will
be interested in. It contains among other basic things, operator
classes required to index jsonb. All of my examples will still not
work, plus a bunch of cases that currently do work reasonably well.
There'll just be a different error message.
