I'm not sure anyone has mentioned what are probably the biggest uses of

not be very useful.

Serious backup systems (programs designed for the purpose) save and
restore the old value of atime.  'tar' has --atime-preserve.  cpio has
--reset-access-time.

Unfortunately those do more damage than good, since incremental backups need to be based on ctime changes and resetting the atime updates ctime.
