That is fine.
superuser can bypass all permission checks.
superuser can attach any table to the partitioned table as he wants.

for example:

begin;
create role alice SUPERUSER;
create role bob SUPERUSER;
GRANT all privileges on schema public to alice;
GRANT all privileges on schema public to bob;
set role bob;
create table at_partitioned (a int, b text) partition by range (a);
set role alice;
create table at_part_2 (b text, a int);
set role bob;
alter table at_partitioned attach partition at_part_2 for values from
(1000) to (2000);
rollback;

Am I missing something?
