I would pay a premium for a system that never gets any new features except for bug & security patches. In fact, that's more or less what iOS was for a long time, and I loved every second of it. Once you have a good feature set, you can spend years and years ironing out 100% of the bugs and vulnerabilities and you'd build a rabid fanbase of crotchety tech-saturated users like me. I want something that Just Works.
iOS doesn't even need more features, it needs way less. Sadly that isn't how the world work. For my one use case I noticed that the newest iOS release doesn't appear to be tested on the iPhone SE 3. The "Press home to unlock" and "X new notification" texts are now laid on top of each other on the lock screen. You're looking right at it when picking up your phone, so you can't miss it, yet Apple QA did.
BTW debugging still takes a lot of effort to setup in VSCode / or have to write init scripts for GDB which I suck at. I think Visual Studio debugger beats everything on Linux for that purpose.
Maybe I really need to try out Windows LTSC?
