IPv4 Protocol 84 Question - why duplicates

Looking at the IANA IPv4 Protocol assignments I have to ask what is up with 84 as it could be either TTP or IPTM, whats up with that and why didn't they give TTP and IPTM unique protocol numbers?

Never saw the need to... at a guess. Probably buried somewhere in some obscure IANA meeting notes
why they did this...

As to not leave an unanswered question lingering here I got in touch with the guys at Rockwell Collins and had an interesting conversation about this, but to summarize all of the computers and radios using TTP are long since gonzo but even recently (2011) IESG wanted to keep TTP and IPTM listed for 84, no doubt the result of a decision by committee, but the fact remains that TTP is deprecated and protocol 84 really only means IPTM (Internet Protocol Traffic Manager).
