the only reason we cannot is gdk_window_resize(toplevel) not taking
over the new width/height right away, and i don't see a good reason for
it doing that.
in general GTK_RESIZE_IMMEDIATE should work fine for any container,
including toplevels, as i replied to owen, code shouldn't rely on
resizing occouring asyncronously (at least up to now, if we want to
change that for the future, that's a different story).

no it can't be ok for any type of window as long as gdk_window_resize(toplevel)
doesn't store away newwidth/newheight.

can you explain why you think override redirect windows should be any
different here than normal windows?

GTK_RESIZE_IMMEDIATE is actually about resizing speed, unrelated to
configure event handling in gtkwindow.c code. there's no particular reason
for GLE selector to be GTK_RESIZE_IMMEDIATE other than that way i got
at least one window that tests whether GTK_RESIZE_IMMEDIATE still works
in gtk.
