 If you're a client developer...that last sentence hits hard.  

A user changed their profile pic URL to a broken link.  Do I continue to show the old one, just because I remember it, and the user is familiar with it? 
 It’s not hard, IMO. Give both people options. Let people change their declared profile pics. Let recipients decided which historically declared profile pic to view. There doesn’t have to be exactly one solution for everyone.
