For mountain areas there has been some use of

place=region + region:type=mountain_area

Much of this data is however somewhat questionable due to lack of 
verifiability (exception being the Alps where there are fairly well 
established conventions of the boundaries of the subdivisions).

In principle infering approximate extents from mountain areas mapped as 
nodes based on relief data is often possible.

An alternative and possibly more specific and intuitive way of defining 
mountain areas could be mapping them as relations containing all peaks 
of these areas.
