The module uses legacy hook_menu() paths. We should figure out ways to convert to the routing system and see how to still attach to the proper places to expose tabs as needed. This may or may not have complications regarding how to make this work with the mix of new routing based modules vs. old hook_menu based modules. Hopefully no specific issues there though.
