It's remarkable how every yearly MacOS release just achieves status 'stable' to use after 12 months and you get FOMO and the next release is already imminent. Please return to the Snow Leopard releases. Take your time introducing great worked out features and polishing the following next year. Stagemanager and many bug introduced features is results of this bad quality releases every year.
Things get rushed...
The problem isn't the speed of OS releases. The problem is Apple letting dev teams commit to features that are not yet stable enough to go in. They need to continue to change incentives so teams hold back things which aren't ready.
Sometimes the impact is unavoidable because it affects _every_ team, like say iOS7 or macOS 11 UI changes, or the rewrite of iCloud to support collaboration a few years ago. But that impact could still be reduced.
If we had a major release every three years again like the early 'big cat' days, but teams still shoved broken sh** in, it would be decidedly worse. The reason to go to predictable 'subscription-style' software releases is to have more trains, so people don't feel they HAVE to make this one, they can wait for the one in three or six months.
The problem is that teams within Apple, either themselves or at behest of management, are taking this as a to push for more velocity - eg. more trains leaving the station, but each needs to be full of cargo. It should be an incentive for teams to take an extra six months or year delay to roll out something of much higher quality. I believe this is a well-identified internal struggle at Apple from prior leaks (I believe iOS 12) - more velocity is not sustainable if it increases tech debt.
With that in mind - if hypothetically the only chance for a software team to get a feature shipped before 2026 was to get in into this September 2023 release, the software quality would be a hellscape. Those issues would also include more fundamental design problems with new features, where fixing them in a point release would not be possible.
People who pine for Snow Leopard forget the negative connotations of the release - that the prior release was SO broken, that they had to take over a year just to fix the bugs.
