[MIRROR] Makes datum stock parts work for Stock parts Experiment purposes 2: Electric Boogaloo [MDB IGNORE] (#18738)

* Makes datum stock parts work for Stock parts Experiment purposes 2: Electric Boogaloo (#72708)

## About The Pull Request
Fixes #72694
#72559 changed the requirements for pinpoint machine scanning
experiments to datums on accident, so to hopefully prevent further
mishaps I've commented the var further.

## Why This Speaks Volumes On The State Of Experi-Sci (Or Sybil RnD)
