Oh yeah, all of that's very much undefined. Every attempt at a "humane" interface inspired by Raskin's post-Macintosh work always stops well before getting to that point.
There may be a much better world of human-computer interaction lurking in these sorts of ideas but getting out of forty* years of refinement of the window-icon-mouse-pointer paradigm, and forty years of building all sorts of tools and toys within it that are not designed to be decomposed into separate actions usable in any context, is a huge effort.
Or there may not, I feel like people have kept trying to do stuff like this over and over again and we just keep on ending up back in the world of monolithic apps that are entire toolsheds worth of tools, each with their own way to do the same things.
* or more, I am counting from the release of the original Macintosh, please feel free to add on sixteen more years if you'd prefer to count from Englebart's Mother Of All Demos, or forty more if Vannevar Bush's Xanadu feels like the place to put a stake in the sands of time and say "modern computing methods began here".
