The only thing that would improve the setup is if iPad could run Mac apps.
Ok, given that using an app designed for cursor precision on a device designed for the VERY imprecise finger would mean that Apple would have to put a limiter on the iPadOS:
Mac apps would only be able to run on an iPad when the iPad is connected to a mouse or trackpad.
As I said in a prior post, navigating an app designed for touch on a cursor-based OS is easy (which is why Apple bought iPad apps to the Mac).
But navigating an app designed for a cursor with a finger is just not going to work right. Even Apple admits to its cumbersomeness...
The zoom-in feature when text editing on iPhone/iPad is a MITIGATION of the imprecise nature of text-editing on a touch device.
This is why Apple went to great lengths to address this via... you guessed it... mouse and trackpad support. It is only natural for Apple to extend that support system-wide, so that other precision-heavy tasks can be addressed more comfortably.
But still, the finger is the primary input method. If you think about it, Apple's primary solution for the iPad's input imprecision is the Pencil, not mouse support.
The Pencil is something you attach and carry with the iPad and is always within reach, unlike a mouse. The Pencil does not detract from the iPad's hand-held nature.
