Don't you mean an optimised implementation of the filter?

How can it be fundamentally wrong if all linear convolution operations can
be expressed in the the transformed domain, and vice versa.
If there is a problem it is not due to the fundamental nature of the
But I will query your analysis first because it may be that we are talking
at cross purposes.
IMO what you have identified is the potential for optimising the code.
This is definitely something that should be addressed if it indeed turns
out you are correct in your analysis.
Although I have strong reservations given that 3 different DSP engineers
