I see no reason to get rid of "dead" tokens in my wallet. Let them remind me of a certain work done earlier. Moreover, there are many types of tokens that wake up a long time after we assigned them to the category of “dead”.
It seems to me that it will be easier to create a new wallet than to mess with removing unnecessary tokens. This problem can occur if there are a lot of tokens in the wallet and you want to clean up the mess. Then they can be sent somewhere, or made invisible.
