It's more than just automating the calling of PyInstaller. It also fixes some edge cases with PyInstaller-built apps that lead to crashes on some users' systems and took me months to figure out. Further, it integrates the solutions nicely. You don't have to learn how PyInstaller works, fbs does it for you with very reasonable default settings. You don't have to figure out how you are going to ship resource files and access them from within your app, etc. Yes you should use the AppContext. You don't have to convert your entire app to it. Only enough to "start" your app. (I highly recommend the app context approach where possible however, it's just so clear.)
