I see no reason for such an option.  And no reason
for the broken default behavior that the original
complaint was about.

Is using `line-beginning-position' here really
something you think is useful?

My vote is to use what I suggested, or similar:

(progn (goto-char end)
         (when (bolp) (backward-char))
         (line-end-position))
