Completed series Covers

[HEXAMENDLE]

Was wondering if for complete series must the Cover be changed to the 1st volume for spoilers
My Hero academia example:-

And if I can, must I report it for the change?

Since the cover for Volume 42 doesn't have any major spoilers (generic shot of all the class and a random kid) it should be set to the default cover instead of Volume 1 per the above rule.

As for the others it would be on a case by case basis, and I feel most reports would be rejected since it's not a priority issue.
