This, if it happens, will be exactly opposed to the IPv6 design goal, which was to discourage/prohibit hardware/software designers from making presumptions or assumptions about the size of prefixes and HARDCODING them into products.
Good point. With current allocation schemes it should work but maybe in the future, for anything outside 2000::/3 it could indeed change and then the above could indeed break.
Hope the implementators of routing engines did notice that unlike what I did :)

2001:0478:: was delegated expressly for IX and core infrastructure.
- - is this documented somewhere? (google on the prefix only returns discussions about it's use ;)
- - is it available to the world(tm) as it looks like this is only
available for exchanges managed by EP as per http://www.ep.net/wtgipa.html
Thus also to the RIPE/APNIC/LACNIC region ?
Regionalizing a root-server shouldn't be the case anyways as it
shouldn't be bound to a certain spot.
I, personally, see absolutely no problem into making it the 'critical infra'
or 'root server' prefix, when it is documented correctly. EP.NET acts as
a neutral body, with this way kinda of a sub-RIR though. All root-servers
should be using the space then btw, not a few, but all of them.
No, no and definitely no!!!
It is one thing to put all IXP prefixes in the same block, after all it does not matter if they are not seen in the global Internet as, in fact, they should not be visible.
However, putting public infrastructure all in the same prefix is about the worst idea I have heard in some time. One hiccup would kill them all at the same time.
