One interesting use case to me would be cataloguing features of an item you own. When you are dealing with insurance, they will reimburse you for a product of like kind and quality. For example, if you have an older consumer stand mixer that uses metal gearing instead of plastic gears (like lots of modern consumer stand mixers), then they might be forced to give you a check to buy a commercial stand mixer that does have metal gears. Adding more features typically means you will get a better payout to replace it - you get Venn diagrams of functionality that only an expensive replacement will fully cover.

I'd love to put in a product code and import functionalities of that product. The data integrity and seeding might be tricky to pull off, but it'd become extremely valuable for anyone going through insurance.
