A loophole, yes; a large one, I don't know. If I remember correctly, the
existence of that loophole is indeed why that remark in red is in the
Values and Units draft.
In general, we try to remove in the new modules all the vagueness that
needs to be in CSS 2.1 to allow the specification to become a Rec. But
not all fuzzy language can always be removed. We usually hope that
competition in the market will push implementers to do the best their
platform allows.
You think the only cases are possible and impossible, and impractical
doesn't really exist?
