I would add that, to be in that category, a keyword needs to be

The rule above is good enough to make a decision in most cases, IMO.

That doesn't contradict category 1.

Do you mean KEYWORD and DESCRIPTION should also belong to category 1?
I'm not against it, but then, back-ends are required to support them
whenever possible.

I don't want to create a third category (à la
`org-element-document-properties', which I'm trying to remove).

That doesn't contradict category 1 either, as shown by EMAIL example.

That's fine as there is no simple way to support SUBTITLE in the
3 back-ends left. Also, the "big four" support it.

We are not maintaining the former and have no control over the latter,
so it doesn't matter.
