It's not practical to have auto-explain on for all queries on a server
which is processing 10K queries/minute.  And non-superusers can't alter
the settings in their session, even the min_duration.

A practical use of auto-explain would involve during it on for a single
user session, or for a specific database user, neither of which are
possible.
