Electrum wallet also have this features now except for Dustin attack feature ( can't verify this ) but I've only seen this feature on Wasabi wallet.
First time I hear about this, but I never had dust attack in any of bitcoin wallets I used.
I wonder if this feature will work after they stop doing Coinjoin in June, but Wasabi will soon become useless, unless some new coordinator appears.
It means no one is interested in your privacy just yet - most dust attack is to track stolen funds and to track real life identity.
