I would strongly discourage researchers from using flippant terms such as "cocktail" rather than more formal descriptors (e.g. "combined" or "integrated" or "multiple", in this case). Careless terminology is likely to invite problematic framings in the discourse, which will then present as obstacles for effective public understand, policymaking, and governance. I am hoping to have have a paper out later this year or next year that addresses some of the challenges around CE terminology and framing.
