Tracking partial identity through tokens is actually a very common concept amongst the newer blockchain platforms which also have addressed such topics as the drawback you describe. While said attack is theoretically possible it only is applicable to tokens managed by the same contract and only on platforms which do manifest tokens as script state (think erc20). Platforms with native assets (Cardano and some others) are immune to such attacks.

where can I learn more about that approach? I just assumed the eUTXO model would be more like the UTXO model where assets could still be tracked to a single address, like with the old Counterparty or OMNI model in Bitcoin. What would you consider Solana's approach to assets? I was surprised to find that each address has another unique address for its balance and possession of any asset issued on that network.

  The key is not in eUTXO (allthough eUTXO is a great piece of work, especially because it solves a multitude of scaling issues in the long run), it is in the ledger's capability of handling custom assets natively. This way a wallet exactly shows you which tokens you own are affected by a contract invocation. I don't know how solana handles assets but I personally stay clear from that ecosystem. Too much VC hype for my likes and way too little decentralization of funds.
