I am not sure if I fully understand this one. Karaf features also use
mvn URIs. Karaf's features.xml can also be used in conjuction with
resource filtering. Like this the dependency management can still be
done in maven pom files.

Is this really that important? In my case it is not.
For my project I created a karaf distributions that needs to be
configured after deployment. The most important configuration item is
the location of the triplestore. I wouldn't want this to be the default
value since it would make upgrading forget about the contents of the
triplestore.

My Karaf distribution also partly uses Clerezza. Attached you can find
the Clerezza features.xml that I have created.
I have to admit that I like the Karaf eco-system with support for
clustering (Karaf Cellar) that I will most probably be using in the
coming weeks.
