I agree with you.

In practical terms, I think that any site large enough to have even a vague
need for two /48s could legitimately claim to be two sites and so not worry.
I think the only potential reason to worry is that the /48 might become the
new "Class C" and network consultants will want to use one per floor, room,
department or whatever.

I suspect we can worry about this trend if and when we see it.
