Your screenshot shows a menu in which features, namely the menu bar, have quite explicitly been removed from the default layout because you are unlikely to use them. You are showing the second tier of a menu structure where they are available if you need them occasionally. If you happen to need them more often you can easily add them to the toolbar.

It's certainly possible, but to me it feels like a junk drawer without too much thought. In konsole, for example, it buries "use dark color scheme," which I'd assume is a fairly common option.
