Just to follow up with an explanation of why this fragment is 
necessary:  the xmpp.remoteservice bundle re-uses the ECF generic 
implementation of the IRemoteServiceContainerAdapter...it does this by 
creating an IAdapterFactory extension (specifically, 
XMPPRemoteServiceAdapterFactory).

This extension is then processed and used to respond with non-null 
IRemoteServiceContainerAdapter in the return super.getAdapter(clazz); in 
the XMPPContainer impl of getAdapter(Class clazz).

So that fragment is now necessary (along with it's dependency on 
org.eclipse.ecf.provider.remoteservice) to get/use the 
IRemoteServiceContainerAdapter for xmpp.
