Which is probably why they haven't built any. They did the math and knew they can't make profit on it so they "announced" 35k model is available but tried to upsell all people who ordered it to more expensive models, and now they quietly cancelled the 35k model without delivering a single one. So they can say "hey we released 35k Model 3 as promised" to save face. But I don't think they can make profit from it so they are forced to sell more expensive models.
I remember reading alleged whistler blower reports about damaged cells going into packs. Perhaps this is the most cost-effective way to utilize the stuff they built in tents.
