True, it's more of a convention about what a good UI should do.
Another such convention is not to move the mouse pointer unless it's
*really* The Right Thing to do.

Yes, it's a convention that is not always followed.  I consider most if not
all of those counter examples as bugs.

Some people sometimes follow the convention that "the geometry as given by
the -geometry parameter should be preserved", i.e. in xterm and Emacs the
number of lines/columns should be preserved rather than the pixel size of
the window.

IMNSHO, at startup, the -geometry argument should take precedence of course
(after all, it's not a question of changing the size but of setting the
initial size), but after the initial setup, any request to change some
aspect of the window other than its size should not change its size.

For Emacs that implies that we should distinguish fringe-changes made in the
.emacs from those made later.
