2008 BMW X5 Front Brakes

Last week I got a notification from the display panel of my 2008 BMW X5 (3.0L) to replace my front brake pads. I was reading posts on these forums as well as a few other forums and was a bit confused regarding the same.

The dealership has recommended changing the rotors along with the brake pads. A few posts I read recommended doing this too since the "newer" BMWs come with 'softer' rotors and they usually get worn out before the brake pads. A few posts went on to say that rotors should be fine. Is there a specific year that BMW started making 'softer' rotors? If not, then is it still mandatory to replace the rotors along with the brake pads?

Thanks in advance for the advice/opinion.
