title: what is the benefit of the taint model over node selector
body: <p>I am learning Kubernetes, and and faced a conceptual question, what is the benefit of new taint model over the simple node selector.</p>
  
  <p>Documentation talks about a usecase where a group of devs might have exclusive right for a set of pods by a taint like <code>dedicated=groupA:NoSchedule</code>. But I thought we can do the same thing by a simple nodeSelector. </p>
  
  <p>To be more specific, what is the role of the effect on this taint. Why not simply a label like the rest of the Kubernetes.</p>
