Yes, exactly. And that is good and I am comfortable with it.

I'm not. But (see earlier threads on testability) saying that an IR is
any resource for which there exists any information whatsoever is
equivalent to saying IR == resource, thus making it a useless and
meaningless term.

Yes and this was a distinction that I was happy to see made, and stopped
opposing the term IR because it was now both useful and testable.
