Is it really worth the effort? I mean if privacy and anonymity are the goals, aren't there better options than CoinJoin? In the other thread n0nce mentioned one could even code in an easier way to add coinjoin coordinators, so you could even have a whole list to choose from. Even if you had a whole list of coordinators, they are each a centralized entity which requires trust in those entities. Wasabi told us they're using BCA, what's to prevent another coordinator from pretending they're not. Would we know?
The problem here is that other wallets will follow Wasabi's precedent, also voluntarily.
Sure, we could just use mixers and that would be the end of it, but we are trying to discourage this trend by demonstrating that actions hostile to the bitcoin community will be punished.
