More reasoning (but please correct me): for foldLeft the curried argument list is needed in order to fix the function’s input type which would otherwise need to be specified explicitly, plus it allows infix operator notation (which is desirable for consistency with the :\ operator). Neither of these arguments apply to mapAsync AFAICS.
