I would just like to have Mojave kept stable for a few years, security updates included. Keep macOS as a solid platform, and add features through apps. That's pretty much all Apple seems to do each release, make new applications and add-ons, bundle them with the OS and call it an upgrade.
I generally agree with the author, I don't have anything else in the Apple ecosystem so most of the new features are largely worthless to me compared to what I have to give up.
