I don't think comparisons with the denatured case are helpful.
Is "ax + b = 0" a quadratic equation? Well, yes, if you consider it to
be a particular case where the coefficient of x^2 is 0. Do you use
quadratic equation techniques to solve it? No.

I agree we don't want to have multiple approaches of doing the same thing,
but I debate whether I am really doing the same thing?

If software nodes are not designed to be a good fit for my kind of use
case, then what are they designed for?
