I just noted, that the consumer_image_styles modules image_styles, which it adds to the jsonapi output do not show up, because of the use of the keyword "links".
They use the syntax: "imageDerivativs": { "links": { "imageStyle1": { ... }, "imageStyle2": { ... } } }. No idea, why that "links" is needed, but it's there and the jsonapi_links module will kill the content. Maybe we can use the jsonapi_extra fields processing to define which "links" shall removed and which can stay.
Not sure. It would be a huge pain to define it, but it would be done only once.

I'll provide a fix for the 1.x branch, which will introduce a ignore list. I just have to figure out the git stuff, as always.
