Mercedes tend to change what options they bundle in the various packages they offer. I guess they look at the demand for certain features and if one is particularly popular, they will position it for maximum revenue. My 2016 GLC has the illuminated door handles, they work in conjunction with the "Follow Me Home" feature which holds the interior and exterior lights on for 30 seconds so you can see your way to and from your house. When I bought Red Ken the illuminated door handles were part of the Keyless-Go Comfort Package. In that package I also got touch locking of the doors using a sensor pad in the door handles and also the ability to open/close the tailgate using gesture control by sweeping a foot under the bumper. Unfortunately, the Keyless Go Comfort Package was only available to those prepared to shell out the extra £2795 required to buy the Premium Plus package and could not be ordered in isolation like the Keyless-Go push-button engine start package.
