A /64 is not "enough" period. Each IPv6 /64 should be thought of as the same as an IPv4 /32. The RFC is still relevant. You are able to be allocated IPs justifying 8-bits per customer (/56) and customers should expect that /56 be the minimum delegated by their providers. The prefix delegation for IPv6 is based on number of separate /64 subnets they might have a reason to use (which can be for many reasons including security and division of traffic and use cases), Not number of individual hosts they may have, since subnet divisions more granular than /64 are not possible.

I never could understand the motivation behind RFC3531. Just assign /64s. A single /64 subnet has 18,446,744,073,709,551,616 host addresses. It is enough. Period. -mel
