I think all games that have OneDrive as "native support" for cloud syncing should be changed to "hackable". Because it's definitively not a native support solution (I remember you that the definition of native support in this wiki is "This feature can be configured natively (in-game or through the game's launcher or configuration/setup tool).").
The hackable definition: "This feature can be added or configured via modifications, console commands, etc. This state overrides any of the other states." is a lot more suitable for this kind of workaround of not having other type of cloud syncing.
