> If there is nothing generic in JuMP

The current version of JuMP does support user cuts (see [the docs](http://www.juliaopt.org/JuMP.jl/0.18/callbacks.html#user-cuts)); however, I did not mention it because the new version of JuMP is removing solver-independent callbacks since there is [plenty](https://discourse.julialang.org/t/cutting-plane-algorithm-performance-varies-with-gurobi-and-cplex/8597/2) of [evidence](https://discourse.julialang.org/t/cut-generation-not-working-lazy-constraints-lagrangian-relaxation/9948/7) that callbacks are not solver-independent.

You can read more about the upcoming changes [here](https://discourse.julialang.org/t/mathoptinterface-and-upcoming-breaking-changes-in-jump-0-19/4874).
