STRICT is used in INTO, so PL/PgSQL users should already have an idea
what it's going to do outside of INTO.

A quick grep suggests that our (the company I work for) code base has
160 occurrences of INSERT/UPDATE/DELETE followed by IF NOT FOUND THEN
RAISE EXCEPTION. So it doesn't seem like an unusual case to me.
Of course, some of them couldn't use STRICT because they are expected to
happen (in which case they can send a more descriptive error message),
but most of them could.
