The following paper looked at using CHAOS queries and other techniques
(traceroute, etc.)  to locate anycast instances:

Xun Fan, John Heidemann, and Ramesh Govindan.
  Evaluating Anycast in the Domain Name System.

I went back to look about rfc5001---the paper says "RFC-5001 is not yet
widely supported".  The work in the paper ran 2011 to 2012, FWIW.

The topic is about DNS and so is relevant, but...  about "put together a
recommendation":  A recommendation about what, exactly?  Framing some
problem (even if that framing evolves) seems important before embarking
on some course of activity.
