Actually, to clarify a bit, dynamic backends will have to remain 
separate. See the requirements (#9) and especially the non-requirements 
(#4) in the REQUIREMENTS file.

So to reiterate, if some internal changes are needed to make it easier 
for you to implement whatever you need and those changes do not 
complicate NSD the changes can be included.  But anything beyond that 
will have to remain as a separate patch/plugin/project.
