Yeah indexPathForNode: does appear to lead to indexPathForElement:, which itself just looks up in _elementToIndexPathMap, which I don't know what is but isn't an OS call so maybe it's just fine?

Yep indexPathForNode: is fine here, it works for supplementaries and for items.

}
UICollectionViewLayoutAttributes *attributes = [self layoutAttributesForItemAtIndexPath:indexPath];

UICollectionViewLayoutAttributes *attributes;
if (element.supplementaryElementKind == nil) {
attributes = [self layoutAttributesForItemAtIndexPath:indexPath];
} else {
attributes = [self layoutAttributesForSupplementaryElementOfKind:element.supplementaryElementKind atIndexPath:indexPath];
}
return CGSizeEqualToSizeWithIn(attributes.size, size, FLT_EPSILON);
