Looking at build data yesterday & we realized that the most installed builds within companies (in order) are:

3. Fast ring

I would bet they might use it on a test machine to make sure that SAP & ERP are still able to run after the upgrade.

I fully agree that this might be the most probable scenario. Not just those tools, but hundreds of other too.
