title: Do I need pipes with ChangeDetectionStrategy.OnPush
body: <p>Now I use pure pipes instead of method calls in templates for performance reasons (I just wrap method calls in pipes)</p>
  
  <p>I noticed that now I use ChangeDetectionStrategy.OnPush and async pipe in all components, hence I want to remove my pipes</p>
  
  <p>Do I need custom pure pipes with ChangeDetectionStrategy.OnPush?</p>
