Is that true of LPF transfer function errors, though?  There's messing up
the math, and then there's doing the right math but with the wrong
coefficients and maybe a missing nth-order term.  As long as the overall
characteristic is that of an integration over tau0, I really don't see how
things can fail *that* badly.
