Well it does show you the turn:lanes that should be mapped in such case, 
thereby it informs you to be in the right lane. These turn:lanes would 
start in an area where changing lanes is legal.

The rule is to split road ways at physical separation, consistently. 
Thus all different data consumers can rely on it.

Fine, you found an issue how a data consumer could improve by 
implementing a specific tag. Open an issue there and ask for it to be 
implemented.
