Fedora is like it or not one of the most influential and important Distros out there.
Fedora is and will always be cutting edge. They early adopt projects and technologies that absolutely become the standard.
No other distro has this much influence. SystemD, Pipe wire, and other such projects are the norm because Fedora pushed it.
And like it or not, Fedora will make this move very soon with Wayland. Wayland is our inevitable future, like it or not.
I don’t see Arch, Debian, and others pushing things like this, but rather falling in line with Fedora.
There will not be a Linus 2, but rather there will be a peaceful transfer of “power”.
Linus is not the Benevolent Dictator For Life of the Linux Kernel.
Linus has already stepped away from developing the Kernel. He did this after an incident to work on his professionalism & mannerisms towards people. Kernel development did not stop. Linus does not approve and merge every patch into the Kernel.
Rather it is more likely that the Lead Maintainer/Developer changes to Greg Kroah-Hartmon, and the project does not skip a beat.
Rest assured with something as important as the Linux Kernel: development will keep going.
