Ciao Rollo
Questions like these are best *not* added as text in a node on OpenStreetMap, but probably as an OSM Note [1].
It should especially *not* be added into the `name`-Tag as you have done here.

The way you have added the (falsely named) node to is https://www.openstreetmap.org/way/570452713, and depending on the router, a `highway=track` (https://wiki.openstreetmap.org/wiki/Tag:highway%3Dtrack) is used for routing.

In Italy, the assumed standard is https://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access_restrictions#Italy
Here, it seems to me that `access=forestry` should be added to the way, hence prohibiting access to the general public, "unless you're a wood worker" (as you've written).

I did change this accordingly in https://www.openstreetmap.org/changeset/160027187, if this is not what you've wanted to achieve, please get back to me!

Happy mapping, greetings from Switzerland
