Now you are getting to what I think is a very relevant point.  I may be
mistaken, but I do not think that it is possible to require that every
message arrives at its destination.  Nor do I think it is possible to
require that both sender and recipient of a message end up with a common
understanding of what has happened.  So "reliable messaging" does not mean
exactly that, right?

Would some of this problem go away if we were more in agreement about what
"reliable messaging" means?

I agree with most of that, but you appear to be associating "reliability"
with "reliable messaging", so I can understand your concern.  But I'm not
ruling out reliability (that would be quite daft!), I'm just saying that
there are ways of addressing it that don't invole requiring that every
message arrive at its destination, and that it is primarily a function of
the architectural style in use as to which solution is the most appropriate.

Thanks.
