I would not like to have it on 7/24 servers. There could be problems

How will that be a problem? They will run once at (shortly after)
bootup and end up with a slightly wrong date in the filename.

A real example: A large organisation names the daily logs (each 1-2 GB) of some servers by date. They exactly contain records from 0:00 to 24:00. After transfer to a dedicated server a cron job uses 'date --date=yesterday' and 'find' to start an analyzing script. anacron cannot solve this, but it will not damage something (just result in some error messages, and/or unnecessary CPU hours in worst case). To make this anacron-proof would need complex bookkeeping and exception handling.
