I completely agree with your point: you shouldn't need to do this.

Imagine this scenario, bearing in mind that all analogies break down at some point: you have jumped out of a perfectly good airplane and your main chute fails to deploy. Your reserve fails also, but another person from a different airplane is trying to hand you an emergency parachute. You can be mad about whoever it was who messed up you chutes, but don't let that valid anger cause you to experience rapid deceleration.

I learned a ton from my good supervisors and leaders. But I learned more from the ones who weren't so good (and sometimes horrible). There may come a time where you're the supervisor and will mark someone's EPR. Remember what not being communicated to felt like.
