I would not say that it is a rule of thumb.  After all, xterm resizes 
itself
when the scroll bar is enabled/disabled.  Also, changing font size does
resize the window to keep number of rows and columns the same in both
xterm and Emacs.  However, as you point out, Emacs is inconsistent in
how it deals with this.  I for one would prefer if Emacs always tried
to keep the number of rows and columns the same.  We should agree on
the desired strategy (keep rows/columns or keep frame width/height) for
Emacs before fixing things like this.
