"Existing" might be a better word.

jsonb will be likely be
pessimal to large serializations.   If you're not manipulating and
searching the documents, why would you use it?  It's going to take
more space on disk and memory and should provide little benefit for
present *as well as future code* .  (note, it will provide extreme
benefits for nosql type uses which is of huge strategic importance for
the project).  json and jsonb APIs should work together cleanly, and
the documentation should suggest which types are different and better
for which cases.

I agree with most of this.
