Feature - Array of Struct

Dear Contributors, We're working on a project and trying to use Array of Struct to query the data on indices (PK or SK). Based on the comments in the source code, this feature is yet to be supported and this class was updated two years ago. Will it be possible to provide an implementation of Array of Struct as you have in the other drivers? We could only use R2DBC driver at this stage. thanks
