We just agreed that address reuse is not a "critical flaw" since it can be done in any implementation like my Joinmarket and Samourai examples, and it can't be avoided by a client if a user has the same seed generating addresses asynchronously on multiple clients.

I'm asking you directly: What is wrong with the WabiSabi coinjoin implementation?  I told you exactly what was wrong with the Whirlpool coinjoin implementation and deanonymized the very first example you provided, why can't you deanonymize any WabiSabi coinjoins?
