Day after day yes

In my point of view, this should be managed by the JCR plugin (not the
persistence manager).

We like to make abstraction by using some layers. It increases the
architecture complexity and code but you are more independent of the
technologies you are using. This choice can be review but personally I think
it is more interesting to make abstraction.

The Graffito complexity can be reduce here : either we want to use the JCR
API in our different content services or we want to maximize abstraction by
using POJO's (like now). If the second solution is our choice, we have to
find a way to increase the Graffito community because it is a big deal.
