I agree with you, except personal preferences get in the way. I would prefer the detached menu bar at the top of a monitor, others like the menu bar on every window, others want neither, or a hamburger menu, or a jumble of confusing tabs, or ... Preferences are my preference. The interface can be switched around and modified, turned off, turned on, completely removed, installed again. Not just the menu bar, but all sorts of interfaces: windows/tabs > checkbox/radio/list/combo/popup-menus and at various levels: virtual system > system > application > document/file > paste/clipboard/shelf > view/drawer. For example, why can't we have different running Apps appearing as tabs within a single window? I think we could have much much richer interfaces.
