I agree that it all depends on who you play with and how much you are willing to put up with. Otherwise you end up trying to control too much of the game.
And the dying question is: who leaves their leaders alone in a hex when the enemy is around? I certain try not to do that.
In the ACW series cavalry has quite a bit more MPs than infantry so it is a real issue. But I did use two cavalry regiments to take out three leaders who were not with units. My opponent needed to keep back a unit for protection and failed to do so. Most armies had a guard that watched over the HQ for just that kind of thing. Call it Provost Guard or whatever players need to protect their leaders.
And yes, routed units cannot take enemy leaders.
