Currently, Tarantool considers the following users and roles as system:

tarantool> for _, tuple in box.space._user:pairs() do print(tuple) end
[0, 1, 'guest', 'user', {'chap-sha1': 'vhvewKp0tNyweZQ+cFKAlsyphfg='}, [], 0]
[1, 1, 'admin', 'user', {}, [], 0]
[2, 1, 'public', 'role', {}, [], 0]
[3, 1, 'replication', 'role', {}, [], 0]
[31, 1, 'super', 'role', {}, [], 0]

System users: guest, admin
System roles: public, super, replication

At the same time, there are places in the code where checks are done against system users/roles e.g.

But the predefined role replication is not considered system, because

tarantool> box.schema.SYSTEM_USER_ID_MIN
---
- 0

tarantool> box.schema.SYSTEM_USER_ID_MAX
---
- 2

tarantool> box.schema.SUPER_ROLE_ID
---
- 31

replication (id = 3) does not fall into the system ID range and is not listed in

Question

Is this intentional (i.e. replication is not supposed to be treated as a system role), or is it an oversight and the role was simply forgotten in the system definitions?
