My rule of thumb for Mac is not to upgrade for at least 3 months after my essential apps report that they work under new OS version.

Agree with this, but it's a pretty sad state of things, considering Apple build its brand on "premium user experience".
HiDPI was broken for me on my external display once I "upgraded" to Sierra. In order to fix the problem, I had to install the most recent beta of the OS - not a move I liked making, but one I felt necessary because my external display is such an important part of my work.
This marks the first time that I've had this kind of issue with a macOS upgrade so soon after release. Lesson learned. Now I plan to hold off, with future releases. These new versions aren't bringing any new features that I care about, in the end, so there's no need for the new & shiny version of the OS anyway.
