Sorry, but that’s double speak.
Asking “what use you make of the report” is the same as asking “why you want the information”.
The user made it plainly clear, as have a number of other users in other topics, that they were able to create particular reports under the previous custom report feature, but the ability to produce those same reports has been lost under the current custom report feature.
How or why a user has created their particular custom report is totally and utterly irrelevant.
Nor should they be forced to justify / explain their custom reports just because other don’t see value in them.
