No, I agree that might be stretching things.  As it turns out, I've
decided not to do it that way after all.  Though it is perfectly
legal and works just fine on printers, it fails in an environment
such as DPS* where scaling and zooming might modify the default CTM
at unpredictable ways.

*By DPS I mean Display PostScript running an interactive view program
that repeatedly executes the Page portion at different resolutions
under user control.

As non-printer environments for PostScript become more common I
imagine such issues may well become important and may lead to some
additional recommendations on what is the `suggested' format of
PS files.
