I'd probably have the areas overlap once I get around to mapping the 
surrounding roadways as areas someday. Data consumers that work with 
pavement areas would need to cope with some amount of overlap. After 
all, amenity=parking areas generally include the space for parking 
aisles (and thus area:highway=service service=parking_aisle), and we 
wouldn't punch a hole in a leisure=schoolyard for a basketball court 
that happens to be marked on it.

area:highway=crossing would be inconsistent with how linear crossing 
ways are tagged highway=footway footway=crossing. Granted, crossing 
nodes are tagged highway=crossing, but I think it would be more 
important for these areas to be consistent with linear crossing ways 
than crossing nodes, which are primarily a compatibility shim when both 
forms are present.
