F20-SC: Yes
Rationale
The selected SCION data plane carries forwarding paths and hop fields in each packet. Transit routers use those fields with local interface/topology and cryptographic validation state; they need not install a separate entry for each final application flow. Control-plane path segments and local underlay routing remain, and this does not assert absence of all router state.
