contrib/ is considered a secondary set of features; I routinely get pushback

any technical work we are talking about here.. There's a very large
presentational difference between having a feature in contrib/ and in core, at
the minimum, setting aside the technical issues (such as the
extensions-calling-extensions problem).
We have an existence proof of this already: if there was absolutely no
difference between having things being in contrib/ and being in core, full text
search would still be in contrib/.
Although presentation was probably the main motivation for moving
full-text search into core, there was good technical reasons for that
too. Full-text search in contrib had a bunch of catalog-like tables to
store the dictionaries etc, and cumbersome functions to manipulate them.
When it was moved into core, we created new SQL commands for that stuff,
which is much clearer. The json doesn't have that; it would be well
suited to be an extension from technical point of view.
(This is not an opinion statement on what I think we should do. I
haven't been following the discussion, so I'm going to just whine
afterwards ;-) )
