That is something your ISP is intentionally doing - unrelated to the
IPv6 specification.
There is no technical reason not to give a static net to a customer, it
doesn't cost more (although some ISP charge for that).

I have a static IPv6 /48 net at home and I only remember those
addresses. IPv4 is still there because servers need to be reachable,
but I do not remember the addresses, too nasty. :-)
