One of the reasons is the way ways are represented in OSM, as arrays of node indices, with nodes maintained separately. This is useful for "ordinary" OSM data, since nodes can be shared between multiple ways, but with contours it just means an unnecessary overhead. In new Kosmos I plan to store contours in binary files, this should reduce the memory consumption.
