I like change
Something that would definitely not cut it for me would be if my GNOME computer somehow felt like Windows 95. It's not that Windows 95 was bad, but interacting with modern GNOME is a lot more pleasant.
Change and variety are good. Devices are evolving. Handheld computers are now dominant. Desktop and laptop computers have high resolution screens with faster processors and memory, window contents are indirectly sent to displays through compositors, and that allows for designing interfaces that weren't possible before.
I'm glad that UI evolved, that modern GNOME exists. I like the tiling system on Windows 11, and the smooth crisp OSX with beautiful fonts and icons. Please give me more. It may eventually happen that user interfaces settle, but that day is not today, and it was definitely not in 1995, thank God.
