For the release of Blender 2.83, we have removed the use of the crosshair cursor for Edit Mode, because it was conflicting with tool cursors.
Instead, we can use other things to help clarify to users which mode is active.
Currently, selection in all modes is orange. But, as you can see above, we already color code different kinds of data in Blender. Object data (mesh, curve etc) is set to green, so we could use that as the edit mode selection color.
