I'm pretty sure that's by design, especially given this tidbit of the
docs:

"Essentially this allows the grantee to "look up" objects within the
schema."

Though perhaps the intention is to change this once we have a means
to invalidate plans.

The docs probably should elaborate that once something's been looked
up you no longer need permissions on the schema it resides in.
