  The question of the renormalization scheme dependence of the $\tau$
semileptonic decay rate is revisited in response to a recent criticism.
Particular attention is payed to a distinction between a consistent
quantitative description of this dependence and the actual selection of a
subset of ``acceptable'' renormalization schemes. It is argued that a
reasonable universal measure of the renormalization scheme dependence can be
formulated, which gives encouraging results when applied to various physical
quantities, including the semileptonic $\tau$ decay rate.
