Just my two cents...logging into a barracks or high grade military loot spawning area generally isn't a good idea. It can be an equally fast way to get killed. I do agree that server hopping sucks, but, having said that, everyone has the option to server hop or not. Even though most of us find it a bit on the "cheap" side of things, I'm not sure adding zones of where you can and cannot log out would be a great option.
Limiting what we legit survivalists can do in order to punish those that abuse a frowned upon high risk/reward strategy (ie, server hopping) is something I would hope is not supported.
