That is the crux of the matter. It's more important to Tesla to put those parts on the line, so they can tout quarterly delivery numbers.
And now they're also seeing the downsides of incremental improvement. It's great in some ways, but for repair and maintenance not so much. At least with the "legacy" manufacturers you have parts separated by model year. With Tesla, they might have cycled through a few part models a year. That adds to the complexity of part sourcing, even before the delivery number issue.
