I appreciate that this is now an old topic, but I flew as a passenger into MAN on Monday, it would appear that compliance with the ICAO regs is now actively encouraged/enforced, as at least on 23R, they've gone to the trouble of blacking out the zig-zag markers and painting over with the solid European style bars.
It's a bit nerdy really, but I'll miss the zig-zags, we've had them for a very long time! I suppose EASA wants everyone to be the same.
