Asking me how do I know that Eurovelo 3 is for tourism or bicycle trekking is like asking me how do I know that Paris is the capital of France. « Is there a sign saying that Paris is the capital of France? May be we should remove that tag, don't you think?... »
You don't need sign post to have a route, do you have a sign post at the intersection of those routes ? https://www.openstreetmap.org/#map=12/45.1485/-4.1705 I doubt that. This is how the Wiki define a route: « A *route* is a customary or regular line of passage or travel, often predetermined and publicized. Routes consist of paths taken repeatedly by people and vehicles: a ship on the North Atlantic route, a car on a numbered road, a bus on its route or a cyclist on a national route. » https://wiki.openstreetmap.org/wiki/Relation:route So to paraphrase this for road biking route : « A road bicycle *route* is a customary or regular line of passage or travel, often predetermined and publicized as such. Road bicycle routes consist of paths taken repeatedly by road cyclist. » And if you don't know then don't tag it and don't manage it.
