I'm not sure how to understand the last sentence.  Why and how are
"fractions made whole again"?

I suppose the outer window edges also change fractions when the window
is resized manually.  Or what am I missing?

Anyway note that we implicitly use a fractional approach when resizing a
frame.  The major obstacles to this are `window-min-height' and
`window-min-width' and fixed-size windows.  Also I'm not sure how to
handle window/buffer specific associations like `fit-window-to-buffer'
and `temp-buffer-resize-mode'.
