No, you could be assigned a /128 and have it function for a single host. However, let's not start doing that as it's pretty brain-dead and the reality is that hardly anyone has a single host any more.

Heather has the corollaries correct.

I'm not sure I disagree, but, I certainly don't feel strongly enough about it to submit a policy proposal. I will say that you are far more likely to get this changed by submitting a policy proposal than you are by complaining to NANOG about it.
