We aren't able to serve images using srcsets to make them responsive because we disable the generation of the image sizes within thumbor, because there are no sizes WordPress can't provide a srcset and you also are unable to set a "Resolution" on image blocks.
Thumbnail generation is disabled on upload due to the additional load it puts on uploading an image but ideally we need a way of generating them even if its just manual so it can be done on a per image / per size basis.
