Maybe not. Here is another suggestion:

- We could by default show messages truncated. Then we could have a an
idle timer that after maybe 2 second showed the message wrapped.

That would stop the annoying jumping caused by messages we still do
not have a chance to see in the echo area because they are overwritten
by later message (often leaving the lower line blank in the echo
area).

The above suggestion would take care of that too.

Recentering go away! ;-)

Maybe that is enough, but it could be combined with my suggestion above.
