Comment (by zabrocki):
I don't think that this is an axiom of graded connected Hopf algebras
since most of the ones that I work with don't have this property (e.g.
symmetric functions). Can we call it a subcategory that satisfies the
additional axiom that `f \otimes g = (-1)^{deg(f) deg(g)} g \otimes f`?
