Doesn't Lindegren & Dravins cover the radio case as well?
The definition is mentioned in Eq. 8.
The only thing missing from the paper, as far as I can tell, is a
discussion of LSR - LSR-K and LSR-D.

And, of course, one may prefer barycentric over LSR velocities when
working on extragalactic data.

This prompts me to ask.

Is there is a paper akin to
Lindegren and Dravins
http://adsabs.harvard.edu/abs/2003A%26A...401.1185L
which addresses the same sorts of issues of
"what do we mean when we say frequency/radial-velocity?"

In particular, a paper which addresses the issues with the contexts of
both the recent IAU definitions about precision of definitions and the
traditions of radio astronomy?
