Sorry I put it off the list, as I wasn't sure you were fully
understand what I was talking about.
I am still not sure why you need to get into those chain of responder
when the delegation should be enough, may be we are completely talking
about different use cases.

Anyway, GNUstep isn't tracking Cocoa's behavior then assumes it as a
correct behavior. It should and only is tracking Cocoa documentations
(Which I, sometimes, think it's kinda, sometimes, stupid)
