It's somewhat important, but not terribly, as most places don't carry out this test anyway. However, some places clearly still do, so it's important to end this practice to offer a modicum of dignity to the victims. It's easier said than done, as law enforcement is rather lax in rural areas where such tests might be common. At least, with government regulations coming in, such practices might be progressively eradicated at government-run hospitals, which, IIUC, rape victims are mandated to visit for clinical assessment.

Not very much. It wasn't a widely used practice anyway, tho I may be wrong on this, so this is just for those remaining regressive judges who still believed in it.
