Something that people need to understand is that the reason this isn't a feature has nothing to do with them "figuring it out". Adobe has some amazing programmers and web designers, and this would be simple to add in. It's not a feature simply because they don't need to add it.
The problem is that by adding this feature, Adobe would lose money from all of the people who would be reminded that they have a subscription. Probably a decent amount of people have CC subscriptions that auto-pay and they don't even remember they're paying. If Adobe started emailing out invoices, a lot of those subscriptions would get cancelled. So they're not going to spend developer time on a feature that would very likely cause them to lose money.
If there was more competition in this space, they might have more pressure to change it, but no company is going to drop photoshop from their procedures because they don't get an emailed invoice.
