Exactly. I don't know how about "big design houses" like Apple, but in my small shop designers _only_ care about static screen stories. They don't care how user will click those icons, how focus will work, how any dynamic aspects of complex UI works.

In past it was "given" by desktop env, now it's all rebuilt in material or other design but without any advanced behavior, it only "looks good on static screen".
