I'm guessing you are not an actual user of the system you are criticizing since you are wrong on so many points. Not my experience at all. Many of your criticisms are simply false. usr/local/bin is fine. OpenGL is an antiquated system that is a poor match to modern GPUs and it too was deprecated for a long time. mDNSResponder did have some issues but we have been past that for many, many years. Never had issues with Mail that a reindex command wouldn't clean up. APFS has been nothing but an improvement in my experience. 32 bit support was deprecated for over a decade. Sometimes it is time to move on. As far as kernel drivers, yes there are still some 3rd party kernel drivers, but the (ongoing) transition to system extensions running in user space is absolutely an improvement.
