Actually, this is not a 'similar key', but the exact key that KDE is 
using to this day.

I think using the exact same key as KDE is the right thing to do, but 
then they should be compatible. That means:
  * Increasing numerical value means increasing priority (no problem 
here apparently).
  * Highest priority is (typically) 10 and lowest 1.

That last point is a problem if you want to dynamically assign 
priorities to the defaults.list entries: in your example you already 
have 6 entries which would cover a good part of the available priority 
range already.

KDE has used InitialPreference since long before XDG existed. So that 
causes me to wonder. Why didn't XDG use this scheme from the get-go? Was 
it considered and ruled out? If so, what were the reasons at the time? 
Don't they still apply?
