Address space is so huge that iirc the only global addresses in use are 2xxx::

Its so huge that it's not needed to use anything else is the goal as far as I see. If it starts with 2, it's global.

Also for routing table reasons. Ipv6 needs to use prefixes to do link aggregation or it just gets too bjg

I can see that, but surely there wouldn't be much difference matching the first 4bits (0x2XXX, 0xfXXX) vs the first 16 (0x0001)?
0:: is presumably all for loopback-type stuff, but I don't see a reason not to use 1:: through 1fff:: and they would be much easier to type/remember/validate for public DNS servers which are needed before name resolution is available.

Not sure on the history of that. It would make things like that easier
