Ok, thanks for the explanation, that makes it a bit clearer. I still
wonder which role the xdg-* tools play though. They're CLI-tools written
in bash, which one might think are supposed to help non-DE-users deal
with those settings, but if you try to use them without a DE running
they won't let you. At least that's true for xdg-settings,
here's an example:

$ xdg-settings --list
Known properties:
  default-web-browser           Default web browser
xdg-settings get default-web-browser
  xdg-settings: unknown desktop environment
