Equivalence is equivalence the rest seems subjective to me - is the glass half 
full or half empty.

The point is they are no more or less harmful.

Can it please be explained how the IMEI URN when used as stated in 
http://datatracker.ietf.org/doc/draft-allen-dispatch-imei-urn-as-instanceid/
Is any more harmful than as the IMEI is used today by over 90% of mobile phones 
in use today worldwide?

The quote is from RFC 5626 which also states:

"3.1. Summary of Mechanism

Each UA has a unique instance-id that stays the same for this UA even if the
UA reboots or is power cycled."

Since the UUID in the instance ID is also static how is this significantly
different in terms of privacy concerns from the IMEI being used as an
instance ID?

You're not demonstrating that an IMEI is just as good, you're
demonstrating that a UUID is just as bad.
