Hello, the prefix_route module was written by SER guys, when Kamailio and SER were split projects, and it uses what we refer as DB APIv2 (specific for ser project), while db_cluster implements DB APIv1 (specific for kamailio project).
>From my point of view, it will be easier to add support for DB APIv1 in prefix_route module than implementing DB APIv2 in db_cluster. I think there very few modules implementing DB APIv2 at this moment (maybe around 5) and perhaps they should get support for DB APIv1.
