okay, that should be clearer in the description. But hiking routes are
often relations, or superrelations. Would it be wise then to use that
option?
For the other usage cases I see the advantage (but I don't think it will
help at all with contour lines, as in how can there be a speedup if no
relation data is present in the data anyhow).
