Apple has said, repeatedly, that they have no interest in building a Surface-style device. What you and other folks want is immaterial, no offense. Don't expect Apple to turn the iPad Pro into a Surface. If that's what you want, buy a Surface.

Apple has staked everything on touch. They aren't going to do a U-turn and add a cursor to the iPad. My argument is really quite easy to understand. I'm sorry if it's over your head, but I can't simplify it any further.
Apple has said things in the past that they turned upside down to sell more gadgets - bigger screen iPhones to iPads that use stylus. This is what they actually did after saying otherwise, so don't discount even a "Surface" style product from them.
Apple has not staked everything on "Touch". They don't sell a single computer that comes with an original touch device, built-in or otherwise.
What is to stop Apple (except Apple) from adding iOS features that accommodate features that make an iPad more like a computer? At the price now, nothing, and, there is nothing physically limiting these features.
Unless you are Tim Cook posting here under a nom de plume, you have not said anything that is backed by Apple's policy - that has changed so much since 2014. Remember when Jobs declared Google his arch enemy - all their iPhones started looking like Android flagships from iPhone 6.
PS: I don't count the Touch Bar on the MacBook Pro line as Apple committing to "touch" - just a gimmick.
