Don’t take it too serious. I did understand the purpose of your example, I just explained why “gift” was a bad choice. Since you very much emphasizes consistent and clear tagging, I think it is perfectly fine for a short nitpicking. I didn’t want to start a needless discussion about that specific key.

No, fuel and payment are not “completely similar” to tagging product groups in a supermarket. If you navigate to a fuel station, but you cannot use the offered fuel for your motor vehicle, this station is entirely useless for you and might even be problematic for your further tour. If you arrive at some shop without cash, but it doesn’t accept your debit card, then this shop is entirely useless as well. But if you visit a supermarket, which doesn’t offer bread and juice, you may still choose apples and beer to satisfy thirst and hunger.

Don’t get me wrong. Despite my comments I might even agree with parts of your statements.

“Gifts” is a bad choice in this discussion. What is a gift? You can buy any article as a gift for someone - from a cup to a car. You can even buy an article in a shop=gifts for yourself, then it is no gift anymore.

Now rejecting the “car” example and assuming we have a similar view about what a gift is in this context: A more or less small object, which an average person can carry on its own and from which the majority of people think it would be a good idea for use as a present, sometimes if they just have no better idea. And I’m sure this view also only applies to sort of modern areas in the world, so it is still kind of a local assumption for an international project (even if it’s not bound to national flavors). Now the particular articles, and let it just be article groups or categories, are such a big variety that shop=gifts is in no way better than or different from shop=supermarket.

You talk about searchability. But natural language, which you call inconsistent for tagging, is exactly the language people use for searching.
