Ha, that's an interesting one.
Xenon's gets you Headlight washers for free, and leather gets you Heated Seats for free, so all you would be missing would be the heated washer jets and low washer level warning. To be honest, I wouldn't even bother about the last two.
In my current Scirocco, if it's cold enough the washer jets still freeze, (even with the full winter pack), and the washer bottles so big, in 2 years the low washer warning lights never come on !
