No, Fedora Workstation 40 does not have minimize and maximize buttons by default/ootb.
Or course my view is somewhat biased, but so is yours. I just know people who are absolutely clueless when it comes to computers and yet they have to for example use Zoom for the odd meeting or Teams.
Most apps using a tray icon don’t necessarily require interacting with it for the app to function (and I never stated that was the case), but beginners coming from Windows (which will be where most users are coming from, if at all - at least that’s my “biased view”) will absolutely be used to tray icons being there and might have used them to access app functionality or at least just to see that the app is still running if it has no windows open.
