This is an interesting thought. Even more interesting was what I learned recently while trying to circumvent this issue. Last week I encountered a similar concern in a project I am working on for UWP. I wasn't sure how to help the user open up the necessary ports. Then I discovered that one can submit in the UWP application manifest the port ranges that the app needs to function properly. Whenever a user installs the app, the Windows Firewall tool opens a dialog asking if it should open the port ranges. As someone who typically works in Unix derived environments, this was a delightful surprise.
