FWIW, there are existing packages which automatically kill buffers that
weren't modified for a certain period of time and are no longer
displayed in any frame (using the buffer-modified-tick). If you combine
that with a modification such that the comparatively limited set of
commands that explicitly open buffers on user request set a buffer-local
'persistent-buffer' variable in them, you can then arrange to
automatically erase all non-persistent buffers without touching the
packages that open such buffers. (However, this would tend to break
third-party modes that open lots of extra buffers -- but how many of
those are there? It's mostly things, like Gnus, that implement whole
multi-buffer applications inside Emacs, I think. There seem to be
arguments in favour both of the local variable to mark temporariness and
the local variable to mark *non*-temporariness...)
