Have we ever left the topic?

There's already an RFC for that http://tools.ietf.org/html/rfc4193
and it's the minimum size for any IPv6 as public key (notice that 
this is tunneled, so routable). For encoding geography, a /64 is quite

It is completely irrelevant. My provider would sustain less than a

It is very possible if every address from that subnet costs you 5 EUR.
