As a host (of the VGC Warhawk League, see my sig for recruitment information :) ), I would love the option of being able to switch from player type hosting to dedicated without having to shut down the server. This would allow me to come and go as I please without breaking the flow for the game for the others. (When you shut down the servers, you lose a lot of people who take it as an opportunity to leave.)
Of course, this would not be an issue if they just brought back the old "feature" by which the disk only served the purpose of booting up the game, so I could take the disk out and boot up my other PS3 to act as a dedicated server. Now when you try to do it, the game automatically brings you to the XMB.
