[Mailman-Developers] Authorization System in Core

Hi, Earlier, while discussing the permission system for manging styles, it was decided that the permissions system should be enforced in the core rather than in the postorius since otherwise it can be bypassed(deliberately or undeliberately). But one thing that I think I forgot to discuss was that currently there is no authorisation system in the core and now I am unable to figure out that how could the permissions be enforced in the core without an authorisation system. Should I workout an authorisation system for the core first or enforce permissions in postorius only?

Thanks, Harshit Bansal
