We would have to specify the respective semantics first.  Atomic
groups by default do not have main windows.  All its constituting live
windows are treated equal - as, for example, two side-by-side windows
showing the diffs of a file.  If we want to designate one constituent
of an atomic window as the "main" window and have 'quit-window' act on
the entire group as the 'quit-restore' parameter of that main window
says, we would have to write specific code for 'quit-restore-window'.

 > I would at least add the fact that atomic groups can be nested,

When I first used the term "nested" I only meant that an atomic window
can comprise an arbitrary number of windows as long as the resulting
window has a rectangular shape.  That's why I asked you to act on the
root of the atomic window instead on the parent of one of its
constituents.  I'm not sure what to say more about this in the manual
- maybe you can propose the necessary change.

I tried to say that now.

I already devote an entire subsection to an example.

Which use case do you have in mind?  The people asking before for such
a feature wanted the layout apply to any frame - that is, side windows
should specify the global configuration.
