I'm not really on board with the proposal at all here; I think it'll
be useless clutter most of the time. I do not agree with the position
that the only use-case for explain(settings) is performance trouble
reports. Moreover, if we start including fixed settings then where
do we stop? People might also want "pg_config" output for example,
and that's surely not reasonable to include in EXPLAIN.
Independently of that, however:

This is both horribly contorted logic (it could at least do with a
comment) and against project coding conventions (do not use the result
of strcmp() as if it were a boolean).
