> Alas, it's much worse for dragging, so e.g. graphic design is problematic.

What kind of dragging operations are you talking about? Drag and drop operations and box selection are no more difficult on a Mac trackpad than with a mouse, and running out of trackpad area was pretty rare even on the pre-Touchbar generation before they almost doubled the size of their trackpads. Drawing might be harder, but neither device is at all good at that task; that's what Wacom is for.
