Guest shipping address specified on checkout isn't transmitted to customer account if that customer leaves checkout and signs up.

Preconditions:

1. At least one product visible on storefront.
2. No authed session on storefront.

Steps:

1. As a guest customer, open PDP of a product from preconditions.
2. Add product to card.
3. Proceed to checkout.
4. Fill out new shipping address form and click 'Save'.
5. Leave checkout.
6. Proceed to sign up page and sign up a new customer.
7. Proceed to checkout and check your shipping address.

Actual result: shipping address isn't saved.
Expected result: shipping address is transmitted from guest session after user signs up.

This behavior might be questionable since we transmit personal data from one user to another, and I'd like some opinions on this. We treat line items in the same way - saving guest cart and transmitting it to a newly signed up customer. However, products aren't personal data.

Yeah, I actually don't think we should fix this, for the reason you specified. We're explicitly not saving this information on guest customer accounts because it's personal information.

Maybe we could do something client-side to make this appear seamless, but that's about as far as I would go.
