Fuck all of that. Linux desktop really could use a benevolent dictator that has some vision and understanding what the average user wants.
It already has these. They're called Linux Distros. They decide the combination of packages that make up the end to end experience. And they're all aimed at different types of user.
Why are none explicitly aimed at the average Windows user? I suspect there's one major reason. The average Windows user is incapable of installing an operating system at all, and new PCs invariably come with Windows pre-installed. This isn't a sleight on them by the way, it's just that most computer users don't want or need to know how anything works. They just want to turn it on, and post some crap on Twitter/X then watch cat videos. They don't have an interest in learning how to install another operating system.
Also, a distro aimed at an average Windows user would need to be locked down hard. No choice of window manager, no choice of X11/Wayland. No ability to install applications not in the distro's carefully curated repository, plus MAYBE independently installed flatpak/other pre-packaged things. The risk of allowing otherwise creates a real risk of the system breaking on the next big upgrade. I don't think most existing Linux users would want to use such a limiting distro.
Unless Microsoft really cross a line to the extent that normal users actually don't want anything to do with windows, I cannot imagine things changing too much.
