I can assure you that this part of the model has not changed at all.
What you are suggesting is -in effect- copying the horizontal spacing
to the vertical spacing as well. For this to work, all vertical
spacing code has to be split in two: calculate rods (minimum
distances) and springs (elastic distances), and then the vertical
spacing pass must be mingled with page breaking.

Right now, page breaking uses systems as a fixed unit that can be
arbitrarily placed on the page.
