You mean that switching to another buffer in a window could change the
nominal height of that window?

I have no opinion on this because I don't care about line-/column values
returned by these functions.  The only thing I do care about is that if
you have two side-by-side windows, the value of `window-left-column' of
the right window equals the sum of `window-left-column' and
`window-total-width' of the window on the left.  Otherwise, windmove's
functions might fail and I have no intention to fix them again.
