So suddenly 2001:478::/32 is handled as an IX Prefix?
Thus we got a new so-proclaimed RIR in the US then making up
their own policies?

2001:478::/32 is a *normal* TLA and it should be handled as such.
The owner could request people to not filter it on more specifics
but they CAN'T demand it. As there is no /32 being announced the
owner of this TLA can simply expect that they are not reachable
globally. The same thing goes for IX prefixes, filter on allocation
boundaries. Thus check http://www.space.net/~gert/RIPE/ipv6-filters.html

Every ISP has a choice to filter or to not to filter, it's your net.

Btw... you peer with 2001:db8::1 from 2001:db8::2, the exchange
fabric dies, you still get a route via your transit and suddenly
all your traffic is going over your transit link.... go figure.
This is something that happened last week on AMS-IX when they
migrated from /24 -> /23 and people announced AND some accepted
the /24 which is a more specific to the /23 and tada your peers
fail odd eh?

Greets,
