Yea kind of. It is deprecated for other reasons. Full story is here: Design draft: fixing deletes and server side copy
Lets say this flag only works if the satellite sends you delete messages. On the satellite side that is just a feature flag and can be turned on and off. We would have to disable / enable server side copy accordingly. They don’t work in combination with delete messages. Which basically means on the current satellites there is no way to go back in time. But can still be useful for storj private cloud setups or any other brand new satellite that never had server side copy enabled.
