Sure ... I can buy an unreliable car that will *probably* get me to work
for $1000.  If it breaks down, I can simply buy another ....It's not
REQUIRED to have a reliable car, but awfully inconvenient not to.

Or I can buy a reliable car for $10,000.  Which strategy do most people who
can afford it take?

You're right, of course.  I was thinking of all the reasons having nothing
to do with the actual existence of a resource that can cause a browser to
display some sort of "can't reach that page" error.  As you point out, HTTP 
has a number of other error codes for these situations.

Because lots and lots of developers say that this is an issue, and many
member companies proprietary web services architectures have or propose a
solution to the reliability issue, and because if reliability isn't covered
in the WSA the developers will use incompatible proprietary solutions, and
the absence of a solution to a commonly cited problem in the WSA will
seriously undermine its credibility in the industry.
