In many cases, the POS software would have to go out of its way to share the itemized receipt details with the credit card processor. There's probably an incentive to get paid for that data elsewhere that overshadows the benefit to the user.

Some of the payment systems do now allow you to associate an email address with cards which gets you itemised receipts at the cost of privacy.

I actually do use this a lot. Have a corp card and corp email and it’s setup with stripe, square, bunnings (an australia thing) etc. to email receipts. For the corp use case its great. Spam that one use corp email all you want, just send me the digital receipts.
