  Tim  _IS_ a yum developer. That he felt surprised by this means you've 
only been communicating with yum devs on the internal red hat packaging 
team not in the community channels related to yum specifically. It would 
make good sense if you want to figure out what apis are important/matter 
to discuss this on the yum-devel mailing list at the very least.

I think it would help everyone if the packaging team was a little more 
outward interacting than it is currently.

Not with just a read-only blurb to the fedora features list but discussing 
DNF with other folks who are explicitly in yum development.
