    Is there any way to get the window manager's decision as regards an attempt
    to place a window without actually mapping the window.

Nope.  There are window managers that have to delay policy decisions until
map time (e.g. a tiling window manager).

    My current method is to map all the windows and wait for the expose events
    to learn what size they actually end up being.  Then those I don't want
    initially mapped get unmapped.

There is no guarantee that a later map won't change the geometry.
