I think we can choose between either full managed app store mode like on ios (no low-level control but full automatic uninstallation + synced settings and such) or Unix-style where you have full control.

Something inbetween the two is worse, you get installers and uninstallers that are half-broken because they can never assume stuff about your system and just be broken but you never know exactly what they're doing.

Windows and macOS are both inbetween to various degrees, but I think macOS is a bit closer to Unix style (excluding App Store apps).
