We don't really know whether doing that will be effective.  Given N
lines of messages in the echo-area, what are the chances that the user
will see all of them, or even the most important one(s)?

IOW, we don't have any real experience with this kind of UI.  We need
to collect such experience first, before we conclude that this could
be used as an alternative to sit-for.
