Although the way is new, don't the nodes along it keep their identity?

Yes, indeed.  If the road is exactly along the forest boundary then you can
again look at the nodes, but if there is some separation between the two there
is no clue in the database.

Yet clearly, tracing a road from the boundary of a forest, when you don't have
permission to distribute the forest data itself under the licence you want, is
no different to tracing a road from the boundary of an object you saw on Google
Maps and overlaid on your screen.

So, sadly, I suppose an 'exclusion zone' would have to be imposed.
