I don't understand what you wrote. ALTER DEFAULT PRIVILEGES also only applies to objects
created by a single role when you grant default privileges.
I think my point is that a paragraph like the following may be a useful addition:
If one wishes to remove the default privilege granted to public to execute all newly created procedures it is necessary to revoke that privilege for every superuser in the system as well as any roles that directly have create permission on a schema and also those that inherit a create permission on a schema. Lastly, any new roles created in the future with direct or indirect create permission on a schema must also be altered. In other words, the first time a role creates a routine the default privileges involved with that creation will including granting execute to public, unless said default privileges have already been revoked.
Maybe generalized to any of the default privileges. I find the existing wording to gloss over the fact that one cannot just decide up front they want to not allow these default privileges to public once on a system-wide basis but must continually maintain the default privileges as new roles are added that are allowed to create different objects, directly or otherwise.
