I would assume the main form is drawn in the position specified.

a '-geometry' option can actually be somehow annoying especially if the
command-line interface has to meet some specs. Checking the .Xresource
file might be more of a general solution, but then all the Forms will
open in the same position and this may not be what you want, unless
there's a mechanism to specify which application should be placed where
(but I have no idea how to do that).

And I concur that no change request should be formulated prior to
understanding if this need is somehow shared in the community or it's
just my laziness in moving the window in the proper place.

Maybe there is a system level approach to that and does not need to be
addressed by XForms, but it's just an hypothesis.
