This is completely backwards. Whirlpool doesn't fix the problem of toxic change, it makes the problem even worse since it creates the toxic change from a self spend transaction (tx0) instead of creating it from a coinjoin where it has the potential to gain unintended privacy by chance:
This is Wasabi 1.0, a bad design from the beginning.
By the way, the pool chosen by the users in your example is not the ideal. The one of 0.05 would accommodate better.
Don't you see how Wasabi 1.0 has the chance to create less toxic change than Whirlpool due to coinjoining the change instead of self spending it in tx0?
