Yes, that's exactly the kind of thoughts I had when reading the
description.  Why do we need to display text from different sources in
the same buffer, when we already have side-by-side display in adjacent
windows?  If the problem is the decoration which set windows apart, it
is a minor issue to begin with, and we can make the separating
decorations less prominent.
