NSUserDefaults bug or feature?

[Kaelin Colclasure]

The commented code in the function below is how defaults are presumably 
supposed to be set under Apple's Cocoa. However, doing it this way under 
GNUstep results in the default values being discarded. GNUstep's 
NSUserDefaults class seems to want all default values specified as 
strings.

void
register_defaults (NSUserDefaults * userDefaults)
{
  NSMutableDictionary * defaults = [NSMutableDictionary dictionary];
  // TODO: File this as a bug in GNUstep?
  // [defaults setObject: [NSNumber numberWithBool: YES] forKey: 
@"spawn"];
  // [defaults setObject: [NSNumber numberWithInt: 1] forKey: 
@"workers"];
  [defaults setObject: @"yes" forKey: @"spawn"];
  [defaults setObject: @"1" forKey: @"workers"];
  [userDefaults registerDefaults: defaults];
}

So is this a GNUstep bug or feature?
