In its initial release, TMON/MVS front-ended the first load module involved in GETMAIN/FREEMAIN after all validation and common entry logic (SVC, PC, branch-entry, etc.) had been processed. The reason was to detect and identify orphan pieces of virtual storage in CSA/ECSA/SQA/ESQA. This function was added to the product before IBM put the same logic into the operating system, so it might not still be in there.

I suspect a large shop such as yours has vendor products that already do it. ENQ has provided exit points so that frontending is unnecessary.
