No, not exactly. If Nokia wanted to integrate automatic opening of Nokia Drive from an address in the contacts application (People Hub), the OS has to be changed. These updates come from Microsoft and are different from the Firmware updates from Nokia for the Lumia.

With the Firmware updates from the phone vendor (which control only pretty low-level functions, as hardware control and so on) no direct features can be added to Windows Phone. The feature updates come from Microsoft. At least that's the way I understand it...
