That's a lot of words to completely disregard the fact that autofocus M adapter exists for Z and E mounts, allowing you to keep the same lenses, but with AF on digital - see Techart. Nikon Z system cooperates best thanks to a thin sensor filter stack, not too far from Leica's.
On vacay I can carry a practical 24-120 zoom and a light M-mount 35mm for portraits or lower light situations, without the pretense.
I just do not understand the hostility where all there is is different approaches. A charitable take (there are plenty) for example would be that I (like many) have about twenty years of legacy gear investment that I need to consider and/or was unaware of the rather recently introduced (2018?) Nikon Z system. You clearly have "a system" that works for you and that is great! Can you even get autofocus on a 1930s Elmar with that setup? Because would just be bonkers to think of from a technical perceptive.
Personally, I prefer to shoot manual to keep the operation the same between film and digital and I am fast and competent enough with a rangefinder patch that I do not feel that autofocus gives me that much and I only shoot primes (28 and 50mm). The Nikon Z system looks really interesting though, so thanks for bringing it to my attention. It is great to see innovation in this space that is not just Fujifilm; I will make sure to try my hands on one next time I am in one of the big camera stores.
