Yes, this is correct and rather inconvenient. But lowering DEFAULT_PREFERENCE 
won't work here, as meta-arago-distro has a higher layer priority than OE-Core 
and hence supersedes the recipe's DEFAULT_PREFERENCE.

It's either keep track of the OE-Core version or convert the recipe to a 
bbappend, like you already did.

Specifically in this case it's not so bad - OE-Core has version 9.0.0 and 
Randolph's updated local version pulls additional commits that were merged 
after the release, making it 9.0.0+git. So, when a new version comes out and 
OE-Core updates the recipe, we would anyway need to remove our local version.
