I completely agree that these are important things
to consider.

This is true, but I can also imagine that there is additional
info that might be useful.  We had the same debate regarding
result codes and roughly agreed that "states" are for systems
and "descriptions" are for humans.

Another point is that perhaps the suggestion wasn't to
modify E2Emon, but rather the MAs that produce L2
status information.  There maybe other clients that
talk to them.
