Yes, I agree.  The intention is that with the passage of time, each
prefix becomes more and more reachable, til it's as close to 100% as any
other IP address.

I was just suggesting a side point, that some kinds of IP users may be
able to make earlier use of measurably less-reachable addresses.  That
could possibly enable them to get those addresses at lower prices (and
with no guarantees), compared to people who want and expect 100%
reachable IP addresses.  Having users making actual early use of them
would also encourage those users to actively work to improve their
reachability, rather than passively waiting til "somebody else" improves
their reachability.  (Indeed, some adventurous early adopters might buy
such addresses, actively improve their reachability, then 'flip' them
for higher prices, as some people do with real-estate.)  Just pointing
out a side chance for a win-win situation.  Most users would wait til
surveys show high reachability.
