I do hope to MFC this work, but it's currently incomplete.

It's part of an effort to make pf support dummynet, and as part of that I'm
also writing a few test cases (which requires the dummynet support). That's
revealed at least one bug (when an interface goes away dummynet does not purge
queued packets for that interface. When it goes to send them bad things
happen.).
I'm also having issues with an IPv6 queue test, but I'm still debugging.

tl;dr: I hope to eventually MFC this, but right now vnet support in dummynet
should be considered experimental.
