They are trying to use a regulator. Essentially it is an LDO schematic. LDOs are supposed to greatly reduce ripple, so they counted on a possibility of using a smaller cap.
However, typically LDO does use some smaller value capacitor at the output.
It could be tried first.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
