I don't think so. To start with your finish:

I think we can as well do this as distributors (either in Debian, or TeX
Live).

Exactly. And this raises the question whether there is any reason not
to write out dvips specials into the DVI file by default, doesn't it?

Yes, but why can we get this magic with PDF, but not with DVI?

And I would actually *not* like to encourage people to hardcode this
driver selection in their files. Too likely they also do it for
graphicx.sty. graphicx.sty is not error-tolerant AFAIK, and documents
will be wrong or fail if you try pdflatex on such a document; moreover
it's not needed with graphicx, and in principle also not with geometry.

That's a superfluous option, IMO it should be deleted from geometry,
since it does not make a difference whether it is specified or not.

Which means we might as well use \ExecuteOptions{dvips} in geometry.cfg
and have working documents without any change to the source.
