These are basically that the truncate, insert, delete and insert
rights for the role creating the subscription. Why would we actually

If a unique system role is the conclusion on the matter, it looks so.

The patch still needs some work before being RFC. From what I can
read, pg_dump still ignores roles which are members of the system role
pg_subscription_users and these should be able to dump subscriptions,
so you have at least one problem.
