title: In a react native section list, is it ok to have duplicate keys if they are actually the same object?
body: <p>I have a section list for sending a message to someone... section 1 is recents and section 2 is all friends. I'm getting the duplicate key error, because the recents are a subset of all friends, but the two objects are actually the same thing and that is the behavior I want. Is there any way to optimize this or tell the section list that it's ok? </p>

  <p>Just wanna make sure I'm optimizing for performance. Thank you in advance!</p>
