Description

This is a follow up for https://github.com/apache/spark/pull/26813.

AQE bypasses queries that don't have exchanges or subqueries. This is not a limitation and it is different from queries that are not supported in AQE. Issuing a warning in this case can be confusing and annoying.

It would also be good to add an internal conf for this bypassing behavior.
