You'd do it the same way you proposed for verbose- eg: BUFFERS OFF, et
al, but, really, the point here is that what you're doing with the JSON
result is fundamentally different- you're going to paste it into some
other tool and it should be that tool's job to manage the visualization
of it and what's included or not in what you see. Passing the
information about what should be seen in the json-based EXPLAIN viewer
by way of omitting things from the JSON output strikes me as downright
odd, and doesn't give that other tool the ability to show that data if
the users ends up wanting it without rerunning the query.

Sure, that'd be fine too.
