Thank you, Owen. I was about to make a really snarky and ill-advised
reply, but you covered all my points much more succinctly and
rationally than I would have. One thing I should point out is that
in my industry alone, there are hundreds if not thousands of networks
which would have to coordinate.
Also, using PP127 space for this would probably step on ISPs using
it for its intended purpose, since some of the businesses involved
are in fact ISPs.
