If an app follows the UI conventions of the system it is running on, there is less cognitive overhead for users. However, with the rise of web apps users have at least become a little more used to interacting with a variety of UIs, though the problem is not entirely eliminated.

We've also eliminated a ton of crappy UI conventions and settled on some common paradigms in all platforms. I remember the four-layer-deep right-click context menus and I kinda shudder now.

There were also some really good ideas that I wish had caught on (I was a huge fan of focus-follows-mouse and I still use the X select-into-clipboard), but the general uniformity of UI patters nowadays is very much calming.

I really like the context menus in GIMP. Much less mouse travel than trying to hit the top of the window or screen.

True.

Main benefit to me is deflecting spurious input. All that Drive By Management.

Instead of explaining the history of ergonomics, the philosophy of ethnography, and our reams of data from usability testing, I'd just point at Apple's Human Interface Guidelines.

Like name dropping Aristotle in debate class.

More serious actors will try harder, lean in.
