None of the village kids knew about Kurama being inside him.

No one knew about Asuma and Kurenais relationship either.

Unless you can prove he became famous for it within 4 years you AND that Orochimaru met him during that time, then there is no error or retcon, because nothing previously established has been changed or come in to conflict with.
