Maybe it's just my imagination, but this seems to be rather typical OS sloppy screw-ups that has been happening with most of apples OS upgrades and even updates with a lot of the versions the last few years.
I think it's not imagination but forgetfulness of the "problems" in the past. There has never been a bug-free release of any OS, including OSX and macOS. That's why the dot releases come out. What Apple is doing, from my perspective, is speeding up the bug-to-fix cycle to be faster. And that's a good thing.
I don't know how they develop an OS upgrade, but I would expect them to keep and develop a good basic base OS and just add and/or make improvements to it. But from all issues, it seems that they almost start over from scratch and rewrite the whole operating system (OS) as if it were completely new, and then incorporate any new changes or improvements, some of which are not properly integrated.
Why can't they just add the OS changes or improvement to an existing OS that was already good and working well???
Hardware changes. New cameras, new processors, new modems, you name it. The integration of hardware and software is much tighter now with all the secure enclaves, etc. So the OS has more changes to take advantage of the hardware. Not a total rewrite, but enough changes that it feels like one.
Also, why do they keep dropping small little features that many of us relied on?
Because they don't agree that the features are useful, or have heard from other users that the features are not useful, or distractive, or otherwise not wanted. They cannot meet every person's design desires, so they listen to those they trust most. I don't know who that may be and I don't always agree with those decisions, but that's how software is developed. I know because I was in that industry for 30 years and we just had to recognize that no matter what we did, somebody would be unhappy. My motto was "distribute the unhappiness evenly."
Maybe they should rethink about releasing a brand new OS every single year and fix ALL the things in a current major version before releasing a brand "New and Improved" OS complete with all its new and incompatible causing bugs.
Again, hardware drives it. Think how the market (stock market, that is) would react if Apple decided to skip a year for iPhones, iPads, etc.
And like Ian, I'm not on an Apple rant but just a queary and a suggestion, and no I don't expext things to change.
Just saying...
