This clarification makes sense and is in general how I anticipated the EIP to be implemented. Currently the EIP doesn't specify that the auth list accounts should be considered "created in this tx" as defined by EIP-6780:

A contract is considered created at the beginning of a create transaction or when a CREATE series operation begins execution (CREATE, CREATE2, and other operations that deploy contracts in the future). If a balance exists at the contract’s new address it is still considered to be a contract creation.

So given that definition, 7702 delegation designations are not "created" during the tx and therefore cannot be selfdestructed.

1. SELFDESTRUCT indeed need to be specified explicitly for 7702 - namely, remove the delegate at the end of the transaction, so that the EOA is left as EOA for future transactions.
2. to prevent replay, it should NOT revert the nonce-bump

[lightclient]

I don't think SELFDESTRUCT should revert the deployment of a delegation designation. It isn't added to the list of "deployed contracts" during the tx for a reason.

Suggestion for two cases that the tests should cover:

1. Set code transaction creates delegation (originally to empty account), same transaction creates contract at delegate address, then calls the delegated account, the code executes SELFDESTRUCT.
2. Delegation exists in prestate, regular transaction creates contract at delegate address, then calls the delegated account, the code executes SELFDESTRUCT.
