I must admit I have never seen none;slight_right in any of the lane tagging. None is only used in cases where there are no arrows on the ground for that particular lane. Furthermore empty is also not a valid value. Empty is only valid in e.g. maxspeed:lanes to indicate that the lane has the default value set by maxspeed. Since there is no default defined for turn:lanes, one has to specify a value for each lane.
Please take a look at https://wiki.openstreetmap.org/wiki/User:Dex2000#zeitliche_Auswertungen_Overpass-turbo-abfragen It contains several OverPass queries for the validation of turn:lanes (the page is in german, but search for turn:lanes) Those queries were used by the German community for their week assignment on turn:lane mapping. In order to express that 1 lane becomes 2 lanes, one could use the proposal http://wiki.openstreetmap.org/wiki/Proposed_features/transit, unfortunately imagic is no longer active on OpenStreetMap. regards m ( a heavy lane mapper from Belgium).
