If there is a possibility that all (or almost all) transactions could potentially have their privacy reversed then it will be as you said most concerning from a user perspective. We do not know whether the Chipmixer retained user data while claiming anonymity but the details will be known as and when the law enforcement agencies release it.
If this really is true, then we have to wait some time for this information to be revealed.
Because now, the authorities must be carefully analyzing every detail of these records and checking all onchain movements, as well as comparing them with addresses that they have referenced as suspicious. This will involve long hours (days/weeks) of analysis, which will certainly lead to some time without news about this process.
At this point, it's no longer worth getting desperate. I believe that for the majority of users, it will not be something to worry about, because the authorities will be focused on big criminals who already know that they use Bitcoin as a way to finance their schemes.
