	Why would SR6 be better than any other "underlay" encapsulation here, like MPLS or SR-MPLS? Naively put this seems to trade 4 byte per label with a full 40 byte IPv6 header plus 8 bytes plus 16 bytes per "label". Asking out of genuine curiosity what are those additional bytes in overhead actually buying (except the freedom from MPLS).
