Looks like the application requires macOS v12, which is only a year old. What features does it require that means it can't be backwards-compatible? Is it a SwiftUI thing?
Honestly, dropping v11 for 2.0 was a really tough call. Adopting ExtensionKit, and getting that out the door right when v13 shipped was difficult, but that was the goal we set out for. Supporting v11 made a number of things more difficult, and SwiftUI was some of it. It was not strictly technically necessary, but it made it easier.
