This would be done with a window parameter of the internal window group
window (that parameter would have to be installed by ECB to become
effective) and an appropriate change of `delete-other-windows'.  BTW, I
suppose you mean that C-x 1 invoked within a window belonging to a
window group just deletes all other windows of that group?

Here this is simply `delete-window' applied to the internal window
constituting the group (some other window must be left on the frame to
make this happen).

I suppose you mean saving the group configuration, that is, windows not
belonging to the group are not saved.  This can be done and you can
restore them in an arbitrary window (like the root window of a frame or
an arbitrary other window).

The "other direction" solution will be preferred, probably.  This means
a slight change in testing whether a window `display-buffer' chooses can
really be used.

I suppose we must get rid of all advices.

The more complete the list of issues you sketched above gets, the better
I can try to address these issues early enough.
