did you mean "don't map route=ferry as relation but only if the way
have the route tag put in a relation for all-except ferry ?"

it seem that some mappers are using relation
https://taginfo.openstreetmap.org/tags/route=ferry
https://overpass-turbo.eu/s/Hkz
1569 relation for route=ferry + 239 route_master
osm-carto may of course stop the render of ferry route.
but I don't see the improvement/rational to keep the render with a 
way-with-route-tag but not if a relation is used (in this case, way 
member of course doesn't duplicate relation tag).
the rational is unclear

So the plateform/waiting area for a route=bus is part of the route 
relation but not a plateform/waiting area of a route=ferry ?
I don't see the rational of having differend rules depending
the "vehicule" used.
imho the ferry relation MAY (if someone want to add it) have a role 
plateform
