See the title. Not doing this was breaking adding subscriptions to a manifest on EL9:

19:35:32 rails.1   | 2024-06-18T19:35:32 [E|bac|f4e9a8f2] wrong number of arguments (given 1, expected 0) (ArgumentError)

Considerations taken when implementing this change?

Still needs testing to make sure it works on EL8 as well.
