Agreed that this is not necessary, but it is not objectionable if that
simplifies coding the server side.

I think the important alignment here is being able to trace a client-side
API error back to the service log for further research.  This might not be
a high-volume use, but I have to do this all the time for chasing down
client-side dev issues.  Its easy in DevStack, but in a deployed cloud of
any size not so much.  A timestamp and _anything_ that can map the
user-visible error into a log file is all that is really needed.  We often
can't even do that today.
