This one is clearly specified right now, for SM-aware apps. metacity
should open a dialog when you save session that warns you about
non-aware apps. (It's implemented wrongly at the moment, so you may
not have time to see it on logout, i.e. the dialog doesn't block as it
should. See FIXME in the source code.)

These are the two that are not specified.

That's not a problem though, since the app can just always save
size/position, and the WM can override it in the SM case.

We could say that, except that a) is already specified and fairly
widely implemented, so it would "break" old specs.

See the wm-spec-list thread for details.

There is a clear spec for that, and a number of WMs were fixed after
some wm-spec-list discussion a year or so ago. So you can clearly
establish which WMs are buggy here. Apps should not be trying to work
around the WM in this area, we should just get the WMs fixed.
