I quite agree. There are no other items with, let's say, "drawbacks", or such unwanted effects like Sunfire Cape. Moreover, Sunfire Cape's AoE damage is meant to be a pushing tool for those champions without fast wave clearing potential, rather than an actual damage dealer for opponent champions, do it would make sense that you may turn it off when you don't want / need to push.
