I don't see how.  The problem is what to do with leftover pixels when the removed element isn't a multiple of the character size.  Measuring the frame in pixels does not help when removing, for example, a tool bar that is 1.5 character high.  It is the same problem, what to do with 0.5 character height.  Now if windows are measured in pixels, we can give those pixels to windows, but frames measured in pixels does not help.
