Okay. So the above is an absolute file URL to nowhere.

It means I misunderstood the meaning of the URI.

Yep, I agree. The example I chose did not originate from me, and my
arguments for not doing this were the same as yours. But I was a bit
confused on the interpretation of file:///file.ext URI format. I see it now
as a rootless file URL, and therefore meaningless. I doesn't appear to be
officially deprecated for namespace usage, although it perhaps should be. I
can certainly see a lazy programmer using this for a short identifier, but
unwise URIs similar to this may be too to numerous to enumerate for
deprecation.
