As document shepherd, my proposal is that they simply be removed since they were incorporated as part of a draft merge and it appears that no one has implemented them (other than parsing). [Bruno] Is the option to move those Binding SID IGP extensions in a different (WG) document opened/considered? Any opinion on this? If there is the energy to fully specify usage, than a separate document would make sense. I think there is a enough description of the binding SID in existing SPRING documents. However, it the ERO that is not specified. We could also deprecate types (4-8) in the OSPFv2 Extended Prefix LSA Sub-TLV registry to delay usage of these code points for some time (or indefinitely ;^). [Bruno] Are there reasons to make actions to delay/against such usage? Since these are fully specified in the IGP Extensions, there are probably implementations that parse and validate the sub-TLVs.
