Hasn't menu bar applets crowding with no official overflow menu been a problem with MacOS with an obvious solution (add an overflow menu) for... 2+ decades now? I know third party solutions exist and it's kind of an edge case, but still, I remember encountering this back in the day on my ancient plastic Macbook.
It's much worse than it used to be. Before it was only really a problem with apps with a lot of menus, and you could access the items by switching to an app with fewer of them. Now, the notch takes up a lot of space, and you hit it really soon on a 14" display—I can only have maybe three third party menu applets on top of my collection of built-in ones before they disappear into the notch.
