The observational upper bound on the tensor-to-scalar ratio, $r \\leq 0.036$, implies that the whole family of monomial power law potentials $V(\\phi) \\sim \\phi^p$ are now ruled out in the canonical framework at $95\\%$ confidence, which includes the simplest classic inflationary potentials such as $\\frac{1}{2}m^2 \\phi^2$ and $\\lambda \\phi^4$.
