No, Bart. Those guys know what they are doing, they are not posting here, asking.
My mentor was a High Master pistol shooter, and for .22 pistols it’s clean once a brick or when your accuracy degrades.
Most fellas that don’t shoot competitively don’t have match grade barrels, won’t pay for match grade ammo, and a bucket of bulk ammo will never notice if you don’t bother to clean but at the end of the season.
For every master class competitor in America I bet we can find at least 100 guys that dinged a muzzle or did other damage by bubba cleaning with rubbish tools.
