Some devices seem to need it.
But the delay can be enabled or disabled in the component ..

Some early PIC and AVR devices can lock up if the delay is not present, i.e. if you try and start before the stop has finished being output by the peripheral.
On most newer devices you can remove the stop delay without any issues via the property Leigh mentioned.
