That's only true in theory. In practice, you never have an IIR filter
because you do not have infinite resolution. And in practice, it will
probably be sufficient to precondition the filter in many cases.
Surely the result will not be perfect, but may be good enough to
avoid audible artifacts.

But if you think it does not make sense, I'll leave it as it is.
