I agree.

It’s all written down in RFC 3879.

Trying to reuse the site-local prefix is IMHO not going to have a good outcome, and I don’t think it is necessary.

If OMNI needs its own prefix, it can request that.   The length of that prefix will have to be justified.

Also, I would like to see if Fred can solve the “OMNI” problem using existing addresses, like Global Unicast and ULAs without anything new.   The networks that OMNI is proposing to use could easily get their own provider allocations.
