Comment 2 for bug 1463273

This will make it hard for users to change between mixxx installations (so far it is really easy to switch between any version from 1.8 - 1.12 back and forth). Also at least for cross-platform programs there seems to be an issue conforming to the XDG-standard. IPython tried to use the XDG paths in one of the 2.x versions but soon switched back because it caused more problems for users then solved things. (I can't find the commit explaining the change right now). From what I remember it was mainly a problem with the way OSX handles things.
