Store more information (including name handling rules) for each category

Moving this discussion to a new issue from the Greene King PR:

“What to do with names” is really the final unresolved thing about NSI that I need to figure out before making a real v5 release - you can see on https://github.com/openstreetmap/iD/pull/8305 that we’re running into this same thing with Amazon Lockers (they all have unique names), and on https://github.com/openstreetmap/id-tagging-schema/issues/119 the same thing with cinema chains.

I see three ways to handle a name tag, depending on what kind of a feature we have:

• “strict name” - NSI provides the correct name, and iD should enforce it (e.g. “Burger King”)
• “default name” - NSI provides a name that works as a suitable default, but users can change it: (e.g. “Amazon Locker” / “Amazon Locker - Hemlock”) - I think pubs are like this
• “no name” - NSI doesn’t contain a name tag and takes no opinion on what the user wants to do - bus routes are like this.

I think this information should live in NSI somewhere, so we can remove the iD preset-field hack. I also think that this should be a per-category decision (maybe items can override it), but this is tricky because NSI has quite a lot of categories.

So I’ll be adjusting the file formats a bit to settle on a nicer way to capture more information for each category.

Some more potential candidates for “default names” based on my experience:

All good suggestions! I’d add amenity=cinema to that list too… https://github.com/openstreetmap/id-tagging-schema/issues/119

Is it enough to define a category based only on the feature tag or do we need to categorize individual brands/features?

I’m going to try to make it per-category, but allow override per-brand.

I would consider actually that “Strict name” would be pretty rare. Even the full name of the McDonald’s on the corner of my street is “McDonald’s Lyon Bellecour”. IMHO : we should suggest the base name but allow the user to modify it so he can enter the full name.
