I think the downside (besides the added complexity for probably a small gain), is having to add the weight of the water and/or refill it often.

2 things to watch out for is running empty of water . though if you use a tank with a level sensor you could have a light lite up to show low water level,,needs filling.
The other is keeping the water jet clean and stop any build up , I never went into depth trying to find solution here , I just ended up checking it every 6months or so but maybe there some additive that would help there .
