Ketan, Lots of thanks for a prompt response. I fully agree that if the optical path is IP-enabled, End.X behavior should suffice and there is no need to invent a wheel.

There may be a mix up between the terms L3 adjacency and IGP adjacency. RFC8986 Section 4.2 End.X works for L3 adjacency (with or without routing protocol running over the link) as well as L2 bundle members of an L3 LAG interface. In all cases, the neighbor resolution and handling for IP packets is expected.

The reference to End.X behavior in Section 4.2 of RFC 8986<https://clicktime.symantec.com/15t5ehGnySbVDtJeCDeRr?h=2kOlFMKikknQcZYhSen27l2Xva-hPLCSjS1oRolKuhU=&u=https://datatracker.ietf.org/doc/html/rfc8986%23section-4.2> looks incorrect to me since End.X explicitly speaks about a L3 X-connect and usual Layer 2 helpers ARP and/or ND) would be applicable. But this is not the case for a path for a non-IP path IMHO. I may have missed the details of the response by the presenter, but my gut feeling is that my question has not been answered.
