Yes, but oddly shown to a size that closely matches a real world print out. ;-) Maybe that's not a problem.
Original text for context:
" The viewbox (together with a defined document height and width in real-world units) defines the ratio of user unit to the other units. In a document without viewbox or with non-real-unit document height&width, we have to resort to some arbitrary/default value. This default value might be what Krzysztof suggests: use whatever DPI the monitor is using. But that will cause non-viewbox documents to be shown with different sizes (mm, in, cm,...) on different machines."
What will happen (in the case discussed in that paragraph) is that I draw a rectangle, set the width of that rectangle to 5mm, send the file to a friend, he opens it, draws another rectangle 5mm wide next to it and the sizes will be different. Because the "user units" to real-world units is set according to monitor DPI. This will then also not be close to a realworld printout. I'm arguing that the scheme proposed is not such a good idea. (note compatibility with older files, and default files now that have no proper definition of userunit to real-world)
