I now found the docs to say:
For schemas, allows access to objects contained in the schema (assuming
that the objects' own privilege requirements are also met). Essentially
this allows the grantee to “look up” objects within the schema. Without
this permission, it is still possible to see the object names, e.g., by
querying system catalogs. Also, after revoking this permission, existing
sessions might have statements that have previously performed this
lookup, so this is not a completely secure way to prevent object access.
So, this seems to be perfectly fine.
