Highly capable touch-screen sensor-rich portables are carving out their own niche and that's been a great opportunity for shaking up some of the core ideas in system architecture and OS designs. This applies across all vendors for products in that class. Not only would porting macOS to iPad disturb Apple's business proposition of "why not buy both?" but it would let up on the pressure that makes iPadOS itself evolve and solve problems in its own way. I'd say just be patient and tablets will become what you want. The road to get there is a bit longer than "just port over the old stuff!" but that long road will probably keep surfacing exciting new innovations and paradigm-changes along the way.
