How about I tone this down just a bit (it almost sounds like a
disclaimer!) and say:

  The terms and definitions used in this document are intended to
  increase the clarity of this document. Be aware that some
  definitions may differ (slightly) from usages in other contexts.

I'm not strongly opposed to this, but also kind of feel like this a
given and goes without saying.

I just went through the document searching for ISP, and I think in
most cases, the current term ISP is correct, as the term is used
generically. Indeed, I think using "upstream" would be wrong. (There
are a few places where adding "upstream" seems like a good
clarification, but this is mostly in the context of address
delegations.)

Thinking a bit more about this, what exactly does the term "Upstream
Provider" (as you are thinking) mean? Is this just to indicate where
the address block comes from (i.e., out of an upstream's aggregate),
or does it mean more than that, e.g., where one gets transit from?

I agree that something about this needs to be added.

Hmm. I'm somewhat surprised to note that NAT isn't even used in the
document!

I wonder if we then need to add a section (somehow) that points out
that NAT avoids renumbering pain, but then also list some of the
standard reasons why NAT is not recommended as the solution to our
"problem".

fixed.

fixed.
