Pipewire is a modern audio server that can drop-in replace the mess that is alsa, pulse audio, jack, etc.
Wayland is a communication protocol made to be a replacement for the X11 protocols, with it’s compositer implementations being the replacement for Xorg.
In what way? Like a home partition?
Home should just be a folder you can copy over in most cases.
If it’s a separate partition, most distros can just install to the other partitions without overwriting the home partition.
Ubuntu is not Arch Linux. The 6 month release doesn’t give you the “the newest, best and most shiny versions of everything” in the first place.
If they don’t like change so much as to not being able to handle some minor UI updates, then their better off using a Chromebook lol.
You’d just be making it harder for them move from the outdated software in the long run, because literally everything changes between moving LTS from the 5y EOL period instead of gradually over each major normal 6 month releases.
