For timing purposes on an ILS so you know when you've arrived at the MAP? You don't have to go to the MAP to go missed. You follow the missed approach procedure on the plate. What if you cage a needle shortly after starting? You are REQUIRED to go miss from that point. Here is a random ILS I picked.

If it tells you to do a turning climb then you are safe to do so as published. Where you go missed on the approach once established doesn't matter.
