EIP-7702: Set EOA account code

EIPs EIPs core
407

If a code reading instruction accesses a cold account during the resolution of delegated code, add an additional EIP-2929 COLD_ACCOUNT_READ_COST cost of 2600 gas to the normal cost and add the account to accessed_addresses . Otherwise, assess a WARM_STORAGE_READ_COST cost of 100 .

This seems to suggest that each CODESIZE and CODECOPY operation adds another 100 gas. That’s not great for copying strings. Are those the applicable "code reading instruction"s, since EXTCODESIZE and EXTCODECOPY do not resolve to the implementation? Or is it a remnant of an earlier specification where EXTCODESIZE and EXTCODECOPY resolved to the implementation?
