Please excuse me if this is a FAQ, I just didn't find an answer in the
wiki (possibly because it is obvious) ...
In topological GISses like grass, borders are shared between adjacent
(vector) areas. However, I wonder how adjacent areas should be digitized
in OSM (let's say, forests and farmland,

Yes and no.
Normally we don't map the borders between areas - we map tha areas
themselves. So you would have one way that encloses the forest, and
one way that encloses the adjacent farmland, and they would "meet"

Well, let's say that this is also controversial and we had that
discussion before.

Says who? The boundary of the forest IS the road. :)
This is one of religious discussions - both sides KNOW they are right,
and no amount of discussion is going to change things. Unless we have
a central decision making force of some sort lay down the law, (in OSM
- hah!) you'll continue to see

this is what you say. I say "sharing nodes of the forest and the road
is actually the correct way to do it." Why can't

In the beginning, I thought the same. Now I keep the node separate.
It is just too cumbersome if you have to separate them later on. And
you often have too
