RFC6177 specifically recommends a /48 to /56 because future security measures may require subnetting, even on home networks (eg having IoT devices on a secure DMZ).
Basically, giving out a /64 is the modern equivalent to ISPs saying "you have to pay extra to have more computers on the internet and you're not allowed to use NAT" that was actually a thing up until the mid 2000s.
The frustrating this is that there's no reason to do a /64 as IPv6 was literally designed to hand out huge IP ranges.

Not following recommendation from RFC6177 by allocating a perfectly valid /64 (it being inconvenient to some is another story) is not "violates the documented standards"
