Yes, that seems to be true, even though it's not a security hazard.
After all you are allowed to load a page from another server in one of
your frames, which is an analogous case.

Another oddity is that importing XML through
document.implementation.createDocument or MS.XMLDOM *does* allow the
loading of data from another server, even though reading the data
isn't allowed.

I'd hoped to write a simple script to import and display RSS data from
a few choice sources, but that seems to be out of the question.

Not on my machine (though I have multiple IE's installed, which could matter).
