    Gyan> Understood.  Most operators would like to use ULA for SRV6
deployments so do we need to carve out block out of ULA space just as we
are doing for GUA to conform with RFC 4291.  ULA has is a big enough block
FC00::/7 so we could carve a block out of that.  Does not need to be as
large a block allocation for SIDs as it would not be advertised to the
internet does not require to be globally unique.
