Well, orders were opened 2/28, deliveries prob. a week later, I believe insideevs estimates U.S. deliveries in March ~10k and not all of them were SRs. So, I thought that is not all that there is to it with so many people bugging Elon on twitter about his $35k promise, so many of them should be getting deliveries now or still getting their finances in order, 200k high trims were delivered so far, so I think there's got to be more to it than 10k SRs.
Also, those inventories you see they may not be stagnant, but getting replaced daily with new cars and getting assigned daily to those people whose turn came up. If you see cars on the lot it doesn't necessarily mean there's no demand.
I believe the new process was said to be that all cars are delivered to stores first and assigned to inventory(which you see), only then they are matched to buyers.
