As far as why "site" has been abused to mean "administrative domain",
that comes from the IETF and RIRs being very ISP-centric, as I said; a
single downstream connection denotes a single "site" regardless of how
complex the internal network behind it is or how many other locations it
serves. Or maybe it doesn't, depending on who's talking; that's the
problem.
I think another reason we've often expanded the meaning of 'site' is
because the IETF has never come to grips with the fact that most
multi-site companies (in the geographical sense) have intranets that
interconnect those sites and are multiply connected to the Internet.
Since we don't have an IETF term for such topologies, apart from AS,
we confuse ourselves.

I think it is important for the IETF to have clear documentation of the
interconnectedness of "sites", /48 prefixes, mobility, and freedom of
choice.
We should certainly provide technology that allows freedom of choice,
but the IETF can't do more than that.
At least one RIR now allows ISPs to assign shorter /56 prefixes to
consumer sites, i.e. family homes and apartments. This is not
necessarily a bad thing since it is rare for a family home to turn into
an office without significant infrastructure change. But if there is to
be a special size for the family home, it too should be the same
worldwide. And it too should be documented by the IETF.
Actually the IAB tried (RFC 3177) and the RIRs chose another
approach, which is where /56 comes from.
