As has been explained to Kruw dozens of times, the change output from Tx0s are sent to a separate account and deliberately segregated from your other UTXOs. There is no way to accidentally include them in a transaction. Any user consolidating their change output as has been done in the transaction he has linked to above is doing so deliberately. I understand that Kruw gets angry when people spend their bitcoin in ways that he personally doesn't approve of, but there is no bug here, just Kruw either being deliberately misleading or simply not understanding what is happening.
"Explaned to Kruw dozens of times"?...
You never gave even a single example of why someone would ever want to deliberately create a transaction that causes them to lose their BTC and their privacy:1 - Both Samourai and Sparrow tell you the size of your change output prior to signing and broadcasting Tx0. If you don't want to create a change output of this size, then you go and edit your transaction. This is the expected behavior of any good wallet.
Tell me why you would you ever want to send an output to yourself that costs more in sats to create than it is worth. Any good wallet would prevent you from taking this unnecessary loss.
