I think that the decision on Job-URI versus Job-Id all boils down to a
decision about one of two directions:
1) The solution should solve today's problems easily while potentially
making tomorrow's problem harder.
2) The solution is allowed to make today's problems harder to solve in
order to allow for the possiblity that tomorrow's problems be
easier to solve.
I favor direction #1 which implies Job-Id because I believe that new
technology is most successful when it carries along existing technology
easily. I also believe that it is not wise to make solving existing
problems substantially harder in order to achieve a payback that is not
well understood and may never happen. In my experience, when a feature
is added for some poorly understood future requirement, it is frequently
