I don't know about Andrei's use case, but weak linkage is vital to be 
able to create proper bindings to Apple's SDks. The SDK use weak linkage 
for most symbols. This allows to link with the latest version of the 
SDK, which might have added new symbols, while still targeting older 
versions of the platform. The application then needs to check if a 
symbol is available or not on the currently running platform.
