 All of these alternatives either complicated the otherwise simple data structures or took away useful features (like the dynamically sized portion of the data section).
 
-### EOF validation checking initcode-mode

-Extra EOF validation rules were considered:
-
-- Each EOF subcontainer must either be referenced by an `EOFCREATE` or a `RETURNCONTRACT` instruction, but never both
-- Each EOF subcontainer may either contain `RETURNCONTRACT` or `RETURN` / `STOP` instructions, but never a mix of these two kinds
-- A subcontainer referenced by an `EOFCREATE` must never contain a `RETURN` / `STOP` instruction, whereas a subcontainer referenced by a `RETURNCONTRACT` must never contain a `RETURNCONTRACT`
-
-These rules were not adopted to avoid the extra logic and complexity (esp. the last rule causes EOF validation of subcontainers to not be self-contained).

 ## Backwards Compatibility
 
 This change poses no risk to backwards compatibility, as it is introduced at the same time EIP-3540 is. The new instructions are not introduced for legacy bytecode (code which is not EOF formatted), and the contract creation options do not change for legacy bytecode.
