What possible reason could anyone have for splitting their UTXOs to themselves?
Because I keep the majority of my coins in cold storage and only want to move small amounts at a time to a hot wallet. And sweeping an entire output with zero change provides zero privacy, although I guess that doesn't really matter if you are sending it to a wallet which cooperates with blockchain analysis, lol.
But you only mention this flaw happening in Wasabi and never in Samourai. Why aren't you capable of being honest when comparing?
At least you finally admit Wasabi reuses addresses!
Now show me a Samourai address reuse since they implemented the fixes you linked to.
