Many papercut reducing data features are non-viable today.

For example: a feature on Chase Ultimate Rewards to remember my kids' birthdays in order to default my searches to the right guest ages.

It would be a tiny benefit to me: a reduction of a papercut.

But to get it, I'd have to give highly sensitive information to a party that has no legitimate reason for it.

There are thousands of examples like this, where the small horizontal benefit is not worth the large vertical harm.

Another example: when you buy a new appliance that requires routine maintenance, you can opt in to emails from the manufacturer to remind you to do maintenance… but you'll also get tons of marketing emails you don't want–and possibly not just from them!
