Not really...  at least as long as window widths are required to
be a whole number of columns wide (based on the default frame font).

The total width of the left and right fringe is always rounded up to a
whole number of columns.  So (5 . 0) is equal to (<column width> . 0),
which is also the usual interpretation of (nil . 0) if your column
width is larger than 8 (the minimum no. of pixels required by the
default setting).
