Why don't we worry about reverse recovery voltage and current of a diode in a simple circuit application?
If the freewheel diode was conducting due to inductive stored energy and the switch was closed there would be a current spike. If the switch was solid state like say a mosfet or a BJT then a slow diode will stress the switch more at turn on. If the frequency is high the extra dissipation can be of concern. This current spike can also cause EMC issues.
