So does Asus Zenbook Prime and many models from Lenovo. I have Zenbook and it's almost perfect. Minor touchpad issues, ambien light sensor does not work and screen is always at max bright after reboot, that's about it. The problem of course is that this is fairly expensive machine and people won't tolerate those quirks when enough money is involved.
I have a ZenBook too as my primary Ubuntu machine. It's almost good enough. I also suffer all the points you list, each of which are 100% dealbreakers and perfect examples of how almost it is yet no one goes the extra mile. A little bit of effort/sway from Canonical would go a long way.
then buy certified hardware. thinkpads work great. or go pre-install with system76 or zareason.. the new system76 (clevo shell) 14.1 pro looks pretty sweet (quad core, 16gb ram, half the price of a macbook pro, ubuntu preinstalled) https://www.system76.com/laptops/model/galu1
