      Description

      Good morning,

      Sorry for not creating a more substantial issue, but I hope this will be sufficient.

      In relationship to the following issue, we were working on updating the list of reserved words but it seems as though the website documentation specifically regarding the oracle mode keywords is incorrect, incomplete, or at the very least confusing.

      https://github.com/sqlalchemy/sqlalchemy/issues/7167#issuecomment-952266131

      I have replicated the behavior zzzeek shows in his comment. Per https://mariadb.com/kb/en/reserved-words/ The word system is not a reserved word in ORACLE MODE as the documentation uses "<= 10.3.6" meaning only versions that are less than 10.3.6 have this word as reserved.

      As a result, the following should not trigger an error, but does.
