> Mushrooms specifically are time consuming to clean in any non symbolic quantity.

FWIW, in my ~10 year professional cooking career I think I've washed a batch of mushrooms a grand total of 2 times, only because they were uncommonly dirty. You've probably eaten unwashed mushrooms many times in restaurants. Eating a little dirt probably isn't going to hurt you. If there's anything pathogenic on them a rinse in water isn't going to do much.
