[jira] [Created] (CALCITE-2338) Reconsider the externally visible api of RexSimplify

Zoltan Haindrich created CALCITE-2338:

             Summary: Reconsider the externally visible api of RexSimplify
                 Key: CALCITE-2338
                 URL: https://issues.apache.org/jira/browse/CALCITE-2338
             Project: Calcite
          Issue Type: Bug
            Reporter: Zoltan Haindrich
            Assignee: Zoltan Haindrich

Currently many lower level simplification methods are visible.

While I was porting CALCITE-2247 to a branch near 1.16 I've bumped into an issue because of the fact that by calling a specific simplify method may leave out some otherwise applicable simplifications.

For master there is already an extra safety feature by the presence of CALCITE-2205; it seems like using less entry points may even lead to better simplifications - by changing this; a filter have been removed.
