As usual, different pros have different opinions
. The point to make here is, though, we don't care about slowing down of the diode - which capacitor would certainly do to a Schottky - all we care IN THIS APPLICATION is to minimize (high frequency) noise since integrated voltage regulators are unable to regulate at more than couple of MHz. It's possible that snubber is useful only on regular diodes, while Schottky and FRED types don't need them. Obviously a snubber won't turn a standard diode into Schottky as a general rule, but it might achieve the same desired effect in a rectifier bridge application.
