<blockquote>
  <p>edit: we <em>DO</em> provide feedback on
  migrations to people answering via
  topbar notification</p>
  
  <p><img src="https://i.sstatic.net/l9PMO.png"></p>
  
  <p>The unsubmitted answer would still be
  saved as a draft, since we auto-save
  drafts for questions and answers every
  45 seconds.</p>
  
  <p>However, I'm not 100% sure the draft
  would <em>be visible</em> when you came back
  to that answer. Normally it would be,
  but since we suppress the answer
  editing area on migrated / closed /
  otherwise functionally unanswerable
  questions.. might not be in that case.</p>
