I've always problems in imagining how wide a space is in a
propotional font. For instance, in aligned text (both right and
left) interword space clearly differs from line to line.

I don't think that should be a reason. If you allow something, it
should work in (almost) all cases, not in some. Generally, it will
not work, as you cannot device independently compare pixels with
character cells.
