Not a disagreement with your take, which was helpful to me, but just your parenthetical aside.

Homogenous of degree 0, which is key to the conditions of the results in OP, means f(tx) = t^0 f(x) = f(x)

Thank you. I inadvertently wrote the equation for degree one homogeneity, from memory. I replaced the equation with a link to the Wikipedia page.
