That's quite right. I really don't understand most highway=path tagging, but I'm fairly confident that as far as the cycle map rendering is concerned these are roughly the same thing. Preprocessors have the advantage in that they don't alter the data for everyone else, and they can make judgements that are known to be at least mostly correct for the target use.
