I'm not going to reason from "intersatellite" routing being operational until they offer it in operation. It's feasible, sort of. Laser beam aiming is quite different from phased array beam steering, and though they may have tested it between two satellites, that makes it a "link technology" not a network. (you can steer a laser beam by moving lightweight mirrors, I know. But tracking isn't so easy when both satellites are moving relative to each other - it seems like way beyond the technology base that Starlink has put in its satellites so far. But who knows.

They have been launching laser enabled satellites for a while now. I suspect
that the only way we will really know when they are enabled is when we see
coverage expand to the poles and mid-ocean (unless they make announcements about
it)

I doubt that they would be launching laser enabled satellites that could not
track each other.
