I did post a reply in your thread. I wouldn't recommend doing that, but it can be helpful with toxic change. For instance, when you want to mix 10.4 mBTC, you can mix the 10 mBTC, and exchange the 0.4 mBTC for 0.4 LN-mBTC via submarine swap.
If you want to do this centralized way, better use the non kyc exchanges to send the bitcoin and withdraw in chucks in different btc addresses.
Or just use a centralized mixer, as it'll do it more effectively and cheaply.
What's the point of using a centralized site when you're having an option to choose the other way?
Effectiveness and cost. It appears to be the case frequently, that a centralized mixer can charge absolutely zero, and be even more effective than coinjoins, as your inputs will hold no blockchain connection with the outputs.
Forget to mention it's not really applicable to Wasabi wallet (and any wallet which use BIP 157) where the wallet can obtain relevant transaction from full node without full node knowing which transaction is needed by the wallet.
Correct. Wasabi uses block filtering, so there is no privacy invaded as in regular light clients. I've edited my post.
