These particular bad domain literals certainly *should* be detected syntactically - not by the SMTP checker, but by the convert-to-IP-address routine. (Or by the convert-to-other-transport-address routine, if applicable. And then it might even be legal.) That is exactly the same case as for the "" localpart - only those parties which actually need to understand it should decide if it is syntactically valid, the rest of the world can just as well handle this as an opaque token.
