There will be old features again, like followers used on PvP, militia and laws or super stimpack damage a while after its use?
Super stims causing damage - it means problems, no point in that.
Followers used on PvP - nope.
Militia and laws is the only thing worth of considering but I'm pretty sure it would end up removed again after it becomes just a tool to PK some newbies at exit grid. It would be only useful if some gang wanted to actually guard the town without killing on sight everything that moves.
