in my opinion a more practical aproach is better.
i think they must be independent because is easier to edit and correct 
in the future.
a road around a forest can share nodes or the way can be tagged with 
bouth things, but if i buy land close to the road and take out the trees 
to build a house its easyer to edit just the landuse. so i would not do 
any of the cases.

with JOSM i can zoom and put very close independent paths not touching 
each other making them practicaly coincident.

the only case ill bother about what distance to draw it is if the 
barrier=fence finally gets aproved because maybe the road wich renders 
over the landuse will hide the fence if its to close to it.
 but again is up to each render the width of the road and if it renders 
differet  width upon the number of lanes, there is even less control.
