>Do you mean you would prefer having those tiny blue arrows in cyclosm instead of the blue lane? To be honest, after months using cyclosm, never noticed that these little arrows indicate a bicycle lane.

Well, maybe https://www.openstreetmap.org/way/502506189 looks better 

But it's important that it's not duplicated, separate way is ok too.

>I would consider that this is indeed a protected bike lane

Well, it's not protected if there is no protection. If someone is distracted by a phone or a child on the backseat at 40km/h and crashes into oncoming bike at 25 km/h that kerb will do absolutely nothing (And opposite directions are like 1 meter apart since you have ride at the right side)
