Hi! Primarily, this jam was created for Linux users, but I feel like it's also important that it is open/available to people who're interested in exploring supporting Linux from other platforms. Including a Linux build is a requirement listed in the jam's rules (and has been since 2017). Since that rule is a fundamental part of the jam's identity, I feel that it's important to stick with it.
That said, shipping a Linux build via a packaging tool and learning about the ins and outs of that/discovering and responding to any issues you find can be an important part of gaining the experience needed to support Linux, so I see that as very much within the spirit of the jam.
Hope that helps!
