I mean.... full-disk backup utilities do it all the time.
There are a few different types of full-disk backup, but if it's
file-based and the atimes are modified, that's the intent of the backup
process. The atimes are used to determine which files to backup. A
scrub is not a backup and shouldn't modify the atimes.
