Okay, I mean of course duplicate cycleways where the duplicate mapping
is an error. Correct usages like you present can be filtered out by
looking a the value of the cycleway tag: If there is a separate way and
the cycleway-tag on the road is a track, then it is probably an error.

I would say so, as long as there are not in reality two cycleways (see
above). Wouldn't you?
