Stopped by today, SCE is still buttoning up the work in the back of Target However, 2 Tesla Model 3's were parked at the chargers: one guy was tidying up the charger blocks, and another was working on the white cabinet clusters.
All of the chargers were unwrapped, and the guy was nice. He simply said: "When you see it on the map, you'll know it's open." Guessing this confirms Apr 5 as the target opening, if only because they're on "schedule".
