If users enable Comet with by adding CometSparkSessionExtensions as a Spark extension instead of using the Comet SQL plugin then the offHeap enabled check does not run.
Describe the potential solution
Move the check to CometSparkSessionExtensions or even CometExecRule ?
Fixed by #6195. CometSparkSessionExtensions now makes the off-heap check itself, so an application that registers the extension without the plugin no longer runs Comet on-heap unless spark.comet.exec.onHeap.enabled is set. #6186, which #6195 closed, was a later duplicate of this.
