Yes I really do think you missing something.

LISP is not a core technology but overlay like L3VPN
LISP is pull technology and as such will never provide strigent convergence.

Segment Routing does provide garantee 50 ms convegence, transport for mpls based services (l3vpn, l2vpn,..), mpls optimization and sdn integration.
