Great, thanks!

GRANT ALL would be independently GRANT'ing rights to some role and
therefore unrelated.

This would simply REVOKE that role from the user.  Privileges
independently GRANT'd directly to the user wouldn't be affected.  Nor
would other role membership.

I'm not sure what's being asked here.

I definitely believe it makes sense for a given role/user to be a member
of pg_read_all_data and to be a member of other roles, or to have other
privileges GRANT'd directly to them.

Thanks,
