With mountain ranges there would be a major problem where node should be placed. Carpathian Mountains cover 190 000 km² - good luck with edit wars where node should be placed.

It probably would work better as a separate database.

Many villages or other small human settlements have no clearly defined 
boundaries, and we just represent them as a node. Similarly, many 
objects (say, shops) DO have clearly defined boundaries, but only have a 
node in OSM. In both cases, it's understood that the thing is an area, 
and the node means "it's somewhere around here". 
 
Those are common examples of nodes representing fuzzy objects, and I see 
no reason that a way couldn't also be fuzzy. Just as with nodes, it 
would be up to the consumer to either understand the level of fuzziness, 
ignore the feature entirely, or pass it through and let a human 
interpret it.
