Cognitive overhead doesn't just apply to products we'd think of as simple.
Vim is an example. One of the key benefits of Vim's editing style is that it reduces (one kind of) cognitive overhead. It really does.
You want to delete the current sentence? Just type 'das'. Want to change the text within the quotes? Just type 'ci"'. It allows you to more directly express your editing operations, rather than having to translate them into a number of steps. That reduces the cognitive overhead of that action.
It's also a case where you need a certain amount of training before you can perform the actions that reduce the cognitive overhead. Nothing says that the reduction in cognitive overhead has to be there from the get-go.
I'm not saying that Vim's operation reduces cognitive overhead in all ways, but that it does in one specific respect.
