I think that you are speaking about %% units [1] which
are may be treated "Unitless dimensions" or "relative units" as they 
are just weights of free (available) space.

Such weights are determining final dimensions
of elements proportionally to their values.

%% or 'relative units' or 'free space units' are prototyped from
multi-length units (relative length units) described in HTML [2]
and you are right - their value is underestimated.and little-understood
e.g. no one popular UA has not implemented them, afaik.
