Very small pdfs are edge cases and don't work with most applications.
Historically Adobe Distiller produced pdfs with a minium size of 3bp x
3bp and Adobe Reader 4 required 1in x 1in. xpdf and gs have problems
with files smaller then .5bp x .5bp.

Changing the check in pdftex from <=0 to <0 is trivial, but leads to
other problems:
! Package graphics Error: Division by 0.
I don't think a change is worth the potential trouble.

So you want some kind of error, right? :-)
To be on the safe side with pdflatex, you need at least .1bp x .1bp .
