I never expressed disagreement with having shallow append.

My argument has very good grounding. The "||" UPDATE idiom from hstore
does not and cannot work in a practical way with jsonb's current ||
operator (at least for the large majority of use cases). It could, it
just doesn't. I don't want users to make the same association that I
did, which, based on the total lack of documentation for the new
operator, they easily could.
What is hard to understand about that?
