If both of you feel strongly about that, I'm OK with introducing
something like that.  Now, a routine should be only about waiting on
pg_stat_activity to report something, as for the logs we already have
log_contains().  And a test may want one check, but unlikely both.
Even if both are wanted, it's just a matter of using log_contains()
and the new routine that does pg_stat_activity lookups.
