OK, I see. Well it appears that SimpleFeature#getID should return a unique ID, and the GeoJSON spec[1] doesn’t seem very clear on whether the “id” attribute need be unique or not, so I can see the conflict here. Still, I think the expected behavior would be to make use of the “id” attribute, if present. But I do not feel very strongly about this and in my case I can just use a custom property instead so if you are hesitant I will just let go of this.

I assume this is not by design? No, that is by design. There is no guarantee that there will be an I'd attribute for each feature in the schemaless json without reading the whole file twice. Again if you'd like to add code to take an attribute and use that as the ID then I'm happy to review it.
