EIP-7503: Zero-Knowledge Wormholes - Private Proof of Burn (PPoB)

In the EIP I can read the following:

Cryptocurrency mixers like TornadoCash can successfully obfuscate Ethereum transactions, but it’s easy for the governments to ban usage of them. Anybody who has interactions with a mixer contract, whether the sender or receiver, can get marked.

In this context, people could get marked by using this transaction type. Am I missing something?

Thanks
