It's debatable what peaks/hills belong in OSM. My general rule of thumb is anything that's named officially, and/or anything with a significant amount of prominence and a surveyed elevation. Keep in mind also that many "peaks" shown on topo maps aren't really - they are just survey points where a team measured the elevation. Sometimes these locations don't have any prominence at all - i.e. they don't even stick out vertically.
