Should I keep the online session if joining in progress is disabled?

I have a made a lobby that uses the online session system for server listing. Is there any reason for keeping the session when starting the game if joining in progress is disabled? I mean why should we list the server if it’s not possible to join anyway? I can add also that the server is always shutting down after the game has ended and a new server must be established for a new game.

It is my understanding that the session is in part required for a number of different online functions: achievement, voice, etc. I can’t think of a reason you would not want one around.

Okay, that makes sense. Thanks!
