I support this Draft Policy as re-written.

I shared the author's distaste for the requirement that IPV6 /64s be
SWIP'd, but was not reassured when the discussion veered to consider
prefixes between /48 and /64. AFAIK, ISPs have long been encouraged to
apply for their allocations based on the idea of assigning a /48 to each
'customer' to provide room for unknown technologies, among other things. I
did not wish to endanger that premise, but current language appears to moot
that concern.

To be explicit, to me, "/47 or more addresses, or sub-delegation of any
size that will be individually announced," refers to /47s, /46s, /45s ...
and not /48s, /49s, /50s, etc.
