Hi,

Thank you for your suggestion, but I have no plans to make the suggested change:

- The methods were added to the JDBC as of JDK 9, ~10 years ago
 - drivers that have implemented  these methods would have already added them to their Statement implementation
 - Most implementations of Statement would have more efficient access to the Connection object should they decide to move their implementation to their Connection implementation 
 -  It would be trivial to refactor these methods to their Connection implementation or another package-private class
