That's sufficient reason in and of itself.

It's a pity it's not easier to simply ask ghostscript which fonts are
used, on systems where it's installed. I certainly agree that a full PS
interpreter would be out of place in dvips itself!

I had thought -j because it says `only needed characters' without
clarifying that it doesn't mean `for proper display of the document'
which, after all, is what one might reasonably assume that it does mean.
Though, it does make it trickier that I suspect that, like me, it's very
common that people use DVI tools without realizing that they often rely
on such documents containing important content that isn't `officially'
part of the DVI format.
Thank you very much, anyway. I have appreciated your responsiveness.
