preserve manually added AtomLinks (using addLink on RESTServiceDiscovery field)

We would like to addLink to existing RESTServiceDiscovery field manually in code. Unfortunately RESTUtils.addDiscovery method resets the RESTServiceDiscovery field to the new RESTServiceDiscovery() so all the manually added AtomLinks (using addLink) are lost.

Is it possible to preserve manually added AtomLinks? It could be a simple patch in RESTUtils.java preserving existing RESTServiceDiscovery field (and thus the atom link collection) if there is one already set.
