It seems wrong to adjust tagging because of a particular router.

I would say that you should fix your routing.  If they are service
roads, but you don't want to use them, then you get the route your
policy led to.

I'm guessing you are trying to prevent routes that shortcut through
service roads when such usage would be frowned on.  But at the same
time, if you need to get someplace accessible only via a service road,
that's what you have to do.

Perhaps your router should just have a higher cost for service roads
(somewhat fair, given lower speeds?), or a prohibition on
regular->service->regular, such that regular->service->ferry is ok.
