No you won't.  A delegation is lame if the server isn't authoritative for
the domain.  Leaving out NS records doesn't affect whether a server is
authoritative.  As long as they've configured their servers as slaves for
the subdomain, and Barry allows them to perform zone transfers, they'll be
authoritative.

Leaving out the NS records makes them "stealth secondaries".
