For bicoin, the private key needs to be hot in Wasabi. Note that, this is also true if you merge them in a mix, however that is slightly less problematic, because some blockchain analysis techniques become computationally infeasible. Client-side block filtering works by having filters created that contains all the addresses for every transaction in a block. One can argue that the way to get there would be through education and awareness, shifting the people from the third-set the average Bitcoin user to the second-set those who understand the need of digital privacy and privacy-shortcomings of the Bitcoin network.
