Whenever you change a setting, look up the corresponding “defaults write” command. Put them into a script. Then run that whenever you got a new machine.
This misses the point to an extent that it is honestly kind of insulting. I am aware of how to manage settings, that is not hard or interesting. KLVTZ suggested reverting to defaults on a regular (~annual) basis. I pointed out how changes to my desktop environment are disruptive, regardless of the reason (OS version bumps or revert-to-default).
Settings do not change fundamental OS behavior. I can't set my notifications in Big Sur to "Catalina".
