I know why it didn't occur to me:
- I specifically didn't want to use an algorithm like the one that was
used in the past (when I wrote the code, which started a long time
ago, before adjust-window-trailing-edge') nor like the one that's
currently used. I wanted an algorithm that's more declarative: you
specify the goal, and the algorithm looks for it without you having to
tell it how to do it.
- Even if you have the code to compute the desired shape of the tree, it's
far from trivial to figure out how to go from the current tree shape to
the goal tree shape without bumping into things like window-min-height
and window-min-width on intermediate states.
Actually most of the code in balance-windows-area was written
specifically for that purpose while trying to fix the original
balance-windows (which tended to delete windows in some cases for no
apparent reason). At some point along the way I figured that I could
just as well "compute the goal along the way".
