You mean in general, even for plain old insert/update/delete changes?
Yipes. What happened to ACID compliance?
What I actually expected to ensue was a discussion about how we could
narrow down the effects of a disable-foreign-key-verification switch to
reduce the odds of shooting oneself in the foot. (For example, maybe
disallow it from being set in postgresql.conf.) I wasn't expecting
proposals to enlarge the gauge of the foot-gun ...

Something like
export PGOPTIONS="-c disable-fk-verification=true"
then run psql or pg_restore.
