How large? Because that's actually good because it could show that there's enough user-demand for different implementations of CoinJoin apps.
Not nearly as large as the group that has already upgraded to WabiSabi. ~3x-4x more new volume is coinjoined using the WabiSabi coinjoin protocol compared to the traceable Whirlpool coinjoin protocol, and Whirlpool further splits that tiny amount of liquidity remaining into 4 different pools, fracturing your anonymity set even further.
