You know about SET LOCAL, no? I don't think this argument is very
convincing.
On the other side of the coin, I'm strongly against inventing more than
one new output format for EXPLAIN, and so any argument that depends on
examples such as "xml vs json" is falling on deaf ears here. I think
that we only need an XML option, and so EXPLAIN ANALYZE XML ... doesn't
seem untenable. What other options than those do you really need?
Not ones to add or remove output fields; we'd expect the client to
ignore fields it doesn't care about.
