I asked whether Dired is the only exception, or is there some more
general sign that a buffer could use notifications.  I'm still not
sure what the answer is to that question.  I don't have any doubt that
Dired will work with notifications, but is the only way to have
exceptions is by naming their major modes explicitly?

IOW, I wonder whether your proposed patch could be made more general
in some way.

Thanks.
