Well,

All I can say is that although we have things like parametric, isosurface, and
polynomial - what we don't have is a visual modeler for such things.

There does exist MathMod - which can be quite cryptic, and Desmos - which can
help visualize equations.  But neither have any sort of export feature.

I'm a fan of the mathematical objects - it's probably one of my favorite things
to play with and render - but after over a dozen years of experience, I'd say
that there are usually only a few select shapes that have real, broad utility.

sphere, cylinder, torus, Dupin cyclide, etc.

Now, on the other end of the spectrum, when you need a specialized shape, and it
has to have very exacting dimensions and attributes, then parametrics and
implicit isosurfaces are probably the only things that will fit the bill -
especially when combined with surface displacement.
And those things can be VERY difficult to visualize.

I really like what you're doing, and there are things that I would want, and
would be great to experiment with.  But I don't know what sort of workload is
necessary to make them happen, or what other projects you have to wrap up.

So, ultimately, I'd say that you're going to have to decide for yourself.

We can discuss this more, but I'll leave you with all of that to think about.
