In the app centric macOS workspace, a window is better than a tab but not as good as an app. I have far fewer apps in my cmd-tab app switcher than I have both tabs and windows, so if I can elevate most commonly used things to the app level that’s far preferable to a window. This can be done with a wrapper app, but I’d rather not have to do that.

Under a window centric workspace like Windows and most Linux DEs, a window is good enough, but under macOS it’s not.
