I'd be willing to concede it's at least subordinate to being as such (form and matter are), non-being, to oneness/plurality (form and matter are in some way and they are not each other), and that it's constitutive of the particularity of things with perhaps some other co-principles which one might work out, which would entail that it's contingent at some high metaphysical level (since they're dependent), but it's foundational to reality because it's necessary to even articulate the structure of the world as such as we have it. It could only be conventional or superficial to reality on the condition of some rather odd divine supervenience, but even then we might still be able to say it's *regionally* foundational (i.e. insofar as God creates things *in this manner* then they are of such-and-such a character of themselves).

My BooksIt is precisely “values” that are the powerless and threadbare mask of the objectification of beings, an objectification that has become flat and devoid of background. No one dies for mere values.~Martin Heidegger
