  Many counterexamples to the proposed KSS bound $\frac\eta s \ge \frac 1
{4\pi}$ depend on constructing systems with large numbers of species. As a
result, the entropy density grows large and $\frac \eta s$ can be made
arbitrarily small. However, these constructions do not affect the dimensionless
shear viscosity $\frac {\eta T}{\epsilon + P}$, which agrees with the
traditional $\frac \eta s$ only for vanishing chemical potential. This raises
the possibility that a KSS-like bound holds for all systems, not just
UV-complete quantum field theories, contrary to the previous understanding.
