This would not always help. See for example hw=service way 50330706 https://www.openstreetmap.org/way/50330706 One has to crawl through several service ways to find out that the ferry is connected with the hw=secondary way 475872377 https://www.openstreetmap.org/way/475872377 I see no easy way to implement an algo which would find out that this hw=secondary is the one that "delivers" the wanted road class. I fear this kind of mapping happens quite often. I would expect that the Garmin routing algo is aware of this when it comes to ferry lines, but did not yet test it.
