Besides basketball (which only gives two spots to Europe and Pan America) and football (which only does continental qualifiers) none of the other team sports gives more than 1 continental spot to each continent. Other than guaranteeing Europe more quotas, handball doesn't strike as a sport that needs to do that.
The issue is handball is very Euro-centric which is why you see more European teams at the Olympics, when was the last time more than two non-European nations finished in the top 10 at the world championships?
