Bitcoin Core have slow progress, everything that doesn't have money have slow progress, companies make faster progress. Protecting yourself against the attacks of the nation state is acceptable.
Because when you are working on an important project you must triple-check everything to avoid introducing a single error or crash, that's why you must drive at 10mph, whereas these companies are driving a Lamborghini at 100mph and making reckless decisions like making a sharp turn at a corner and then they flip over and burst into flames, like Celcius, or any of these exchanges that are in financial trouble right now, or even those blockchains that were foolish enough to chagne their proof algorithm and now face an uncertain future (Hi Ethereum).
Whatever chain-anal is sending data to Wasabi wallet already has a record of the sold data and has probably coughed it up to the NSA by now and is being used to correlate wasabi users with whatever other data they have on Bitcoiners.
The end-game is to take action against individual bitcoiners and harass them legally, not to merely trace outputs back to you.
So it is important that the userbase of Bitcoin must
grow in order for their databases to be flooded with so much data that they can't keep a permanent record of them, but only leave them in their stores for a few days. (see
