It seems to me that you are arguing that the scenarios in section 4.1 of the use cases document do not cover that specific case, and I think you are right in that; the list is:

The following considerations are applicable to all use cases:
o Clients can be on IPv4-only
o Clients can be on IPv6-only
o Clients can be on dual-stack
o Clients can be on wideband (10s of Mbits/sec)
o Clients can be on narrowband (10s to 100s of Kbits/sec)
o Clients can be on variable-media-quality networks (wireless)
o Clients can be on congested networks
o Clients can be on firewalled networks with no UDP allowed
o Clients can be on networks with cone NAT
o Clients can be on networks with symmetric NAT

Now, there are two ways to interpret this omission:

- The WG did not think of that use case when the list was created
- The WG does not want that use case on the list because it constrains the solution space too much

If (re)opening this issue, I think I'd find myself in the "do not want that use case" camp.


I do not recall this use case ever being discussed on the working group, so I would assume the current situation is due to WG not thinking about this case when the list was created.
