title: Is it possible to create pip packages for a specific operating system?
body: <p>I just want to know if this is possible. For example, let's say if I want to build a pip package only for Linux or build a pip package for Windows and Mac but exclude Linux, is it possible to do that? Or do all pip packages become available for all 3 platforms (Windows, Mac, and Linux) when they get released?</p>
  <p>Another example, let's say if Stripe wanted to release its Python SDK and make it Mac-only for Python users through pip, would that be possible?</p>
  <p>I definitely would appreciate all answers as I am curious to know whether this is possible! I just want to know if this is possible or not. Thank you to those who do respond.</p>
