As a sibling points out it is a justification for developing in space refueling and orbital fuel depots. Then you could just launch something out of the Earth gravity well, fully refuel it, and then send it on such a trajectory.

Or if we had moon/Mars colonies then we could use standby rockets from them - proximate to humans/resources so we can maintain them but much lower escape velocities.

Adding 4-5km/s dv probably makes intercept and slowdown impractical at interstellar speeds.
