However, without subkinding, kinds have to match exactly, and no choice would be correct if the user expected it to have a different kind. For example, if foo is passed to a generic function expecting a parameter of kind [^] at some point, then inferring the kind [+] for it as above would lead to an error. There’s just no natural choice for inference in the absence of subkinding.
