> Since /64 is smallest network in IPv6
A /64 is not the smallest network in IPv6. Nothing stops you having a /112 or a /126 or whatever you like.
It is the only network size on which SLAAC works however, so it's a good choice for lan sizes.

This RFC has things that may not work properly not to use /64. https://datatracker.ietf.org/doc/html/rfc7421#section-4.2
So from the point of abuse logic it's appropriate to treat the whole /64 as a single unit. (That was the starting point of the thread, even though I realize that due to thread drift that's probably not what your comment was about.)
