Hypersistence Utils (formerly known as Hibernate types - https://github.com/vladmihalcea/hypersistence-utils) provides a CamelCaseToSnakeCaseNamingStrategy which is used in many projects (Maps the JPA camelCase properties to snake_case database identifiers).

It would be great if we could include this in the ORM
