I support adopting this proposal now,  while it is still possible to
allocate the /10.
Even in the absence of policy to  "use this (or RFC1918 space) when appropriate
and technically feasible".

That will begin to happen with the /10 reserved,  due to mathematical contraints
applying to ISPs that need IP addresses, especially when the free pool becomes
exhausted; using RFC1918 or /10 space becomes a more reliably,
inexpensively  available option  than trying to find sources of
sufficient global unique
IPv4 addresses available by 8.3 transfer.
