For someone who "needs"/wants black on black kit...that shiny silver ring is a non-starter.
I am fairly new to the M system but if L doesn't do it why does Z? Just marketing?
Zeiss has done that sort of design for a long time; the Contarex lenses in the 1950s were already in the same design.
The reason was supposedly the superior durability of the hard chrome finish for the lens bayonet; the argument was that the lenses were sufficiently flare-resistant anyway that it wouldn't make much of a difference, and if you were afraid of flare you should use a hood which obstructs the ring.
I guess the Zeiss lens designers didn't care too much about the aesthetics of black on black kits and whether the chrome ring was a non-starter for people who wanted them - the argument being that if in 1960 you wanted the best SLR lenses on the planet, you'd buy a Contarex without asking about the color of the filter ring. It's a bit of a bike shed sort of thing.
