We do not make a distinction between full/non-full bbox requests, there 
is only one type and that gives you all nodes that belong to ways of 
which at least one node lies in the bbox.

No, this kind of spatial computation would only work with something like 
a PostGIS bbox request. (Actually the bbox requests are not tiled in any 
way, you can request whatever you want. Tiles at home requests more than 
they need to hopefully catch cases like the one you describe.)
