Ah, thanks for giving some context. Since I work in an industry that has our main problems being LP & MIP, I can see no reason to not use a general purpose language like Python or Julia to talk to an industrial solver like Gurobi. However, if I worked for a firm that did all sorts of optimization work (I'm jealous of anyone who does this), I might have to determine how best to formulate the problem and maybe MiniZinc is helpful there.
