I think you are totally right. To keep the buffer and window
distinction properly, my note should probably be read as a feature
request, not a bug report. The request is for a function such as
`buffer-body-width' that would return the width of the current displayed
buffer in em-length units.

Sounds promising! I just pressed C-x C-- which runs `text-scale-adjust'
to the effect: "Decrease the default face height by one step". The step
is `text-scale-mode-step', unchanged from its default value of 1.2. The
number of steps looks to be stored buffer-locally as
`text-scale-mode-amount'.
... So a candidate function would be:
(defun buffer-body-width (&optional buffer pixelwise)
(let ((width (window-body-width (get-buffer-window (or buffer
(current-buffer)))
pixelwise)))
(floor (cond
((eq text-scale-mode-amount 0)
width)
((> text-scale-mode-amount 0)
(/ width (* text-scale-mode-step text-scale-mode-amount)))
((< text-scale-mode-amount 0)
(* width (* -1 text-scale-mode-step text-scale-mode-amount)))))))
