We should be moving beyond EOAs, not enshrining them even further (EIP 3074-related)

That’s a great frame for thinking about the problem. Whatever we do, should be a step towards native AA.

This can be done by making a hard fork that edits all existing and new EOAs in-place, replacing them with smart contract wallets that have the same functionality (but also an upgrade feature, so users can upgrade their accounts to a different scheme while keeping the same address).

This is exactly what Optimism does with OVM_ProxyEOA which currently delegates to OVM_ECDSAContractAccount but supports upgrade(address _implementation). OVM creates these proxies on demand when the first transaction is made by EOA. We could use a variation of that.
