title: Renaming .nupkg to .zip
body: <p>We have recently changed our build process to output only .nupkg files and one of our clients doesn't like this idea.I have renamed the .nupkg files to .zip and I can access the files.</p>
  
  <p>My question is... is it acceptable to rename the file extension or will it damage any of the files, compression isn't an issue, so it doesn't matter about that, we just need to be able to give them a .zip version.</p>
