The concern that Jack Erwin raised with me is that putting child
elements in stream features will lead people to expect more of the same,
such as:

<stream:features>
   <dialback xmlns='urn:xmpp:features:dialback'>
     <errors/>
     <dna/>
     <advanced-piggybacking/>
     <some-future-feature/>
   </dialback>
</stream:features>

This is not going to happen. If DNA or "advanced piggybacking" require special signalling then it makes no sense to reuse dialback as a framework. D-W-D for example does not require signalling.
