If you want to restore the frame configuration you have to save it first.
Where do you want to do that?  All I said was that `view-mode-hook' might
be the wrong place.

You can always think of `view-exit-action' as doing that.  For example,
there's no harm setting `view-exit-action' to a function that restores
a frame configuration saved earlier.  The question remains _which_ frame
configuration you want to restore.
