Ello, for those reviewing, everything in the transformers folder is a lift and shift from the simorgh-bff module in fabl. This will be removed later down the line once we get our bespoke simorgh stream module sorted out. I don't think it's all that necessary to review it extensively as it will be removed at some point. Thanks
