Combine Calcite BABEL and DDL parsers

Original problem:
I am trying to parse a DDL statement such as CREATE VIEW V AS SELECT DATE_PART(YEAR, T) FROM TABLE.
If I am using the DDL parser factory, I can parse CREATE VIEW statements but not DATE_PART.
If I am using the BABEL parser factory, I can parse DATE_PART expressions but not CREATE VIEW.
Is there a way to get both?

Hopefully Calcite would accept such a contribution.
The alternative is to fork the project, which would entail lots of maintenance headache.
