DISCUSS:
----------------------------------------------------------------------

Why are there two algorithms (Highest-Preference and Lowest-Preference)?[0]
This seems operationally dangerous and will lead to additional operational
complexity, tricky to debug behaviors, additional implementation complexity,
etc. Assuming that there *is* a good reason (and "Well, we couldn't decide,,
so... ¯\_(ツ)_/¯" isn't one) these should be a section helping operators decide
which algorithm they should deploy, and the pro's and con's of each.

[0]: I did try and find this, but the closest I got was a note in the Shepherd
Writeup saying: "There was a "last minute" agreement on managing the
highest/lowest pref algorithm using different DF algs rather than a single
one+local configs." -- this doesn't actually answer the question.

COMMENT:
----------------------------------------------------------------------

I support John Scudder's DISCUSS, as well as his comments -- the Introduction
seems quite incomplete, and just sort of throws the reader into the deep end.
