why is navigator in a container instead of a package?

[VorlMaldor]

I am trying to understand why navigator was put into a container (EE) instead of just making it a package like everything else.

There are a lot of reasons to not use containers:
added complexity of the install and just the general complexity that comes with containers
having to export volumes for the EE to see your playbooks/inventories/etc etc
added complexity just talking to controller node to run plays

What made navigator inside an EE the way to go? Is it just an attempt to help "encourage" people to use containers more?
What can't be done with an RPM for navigator that required the container?
