Univariate binomial basis conjecture for #P closure properties

Let $\varphi$ be a univariate polynomial closure property of $\#P$, and say that it relativizes when the corresponding closure holds for every oracle version $\#P^A$. Univariate binomial basis conjecture. Every univariate polynomial closure property of $\#P$ relativizes. This is a weaker version of the multivariate binomial basis conjecture and can suffice when only univariate closure properties are needed.
