Except that your name is also put on your doorbell with a label-maker, so anyone in your apartment could easily find out which flat was yours. Furthermore, the downstairs/apartment building's set of doorbells also proclaims last names, and are often ordered by floor. E.g. I live on the third floor, and my doorbell is second highest.
In fact, it's advised that you don't put any first initials/first names on your doorbell, because then people could be inclined to send you prank takeaway food, for example, because they know your address and full name just by standing outside the building.

So...this point doesn't make any sense.
