It causes coq/vscoq#892 because `optwrite` is not supposed to be able to add persistent objects (libobject) to Coq's state but `set_option_value` does add one. It's also bugged as `set_option_value ~stage:Interp (fun _ v -> v) key i` sets the option to its current value not a new value. In other words `Set MetaCoq Template Monad Debug.` has no effect but its existence causes bugs. Since nobody complained about it not working it's not worth fixing it instead of deleting it (also I'm not sure it can be fixed with the currently available APIs).
