The original wording at least implied some level of interoperability, 
I'm not sure "leverage and build upon" does that.  It sound more like 
code reuse is important rather than interoperability.

     REQ5:   SSD should inter-operate with current link scope
             DNS-SD/mDNS protocols and deployments to the extent
             practicable.

I think my answer to the question is bidirectional would be the best 
case.  But, remember these are competing requirements to be balanced. 
So, in the worst case ships-in-the-night meets REQ5 and REQ6.
