Monav never provided routing instructions in the daemon. Just like the monav client application, marble has to generate them on its own. So your critique should be that Marble uses a different approach to generate the instructions.

Kinetic scrolling is work in progress as I said in the post above. The new version has a beta label for a reason, and a similar warning goes for extras-devel. Please use the Marble version in extras if you want a stable one.
