Can I just locally modify the MPBWrapper.jl function on my computer?
Yes.
Is this something you would consider?
Yes! Have a look at the contributing guide (just replace any references to JuMP with Gurobi.jl).
If you’re not sure how to make a pull request: implement the wrapper locally, test that it works, then open an issue on the Gurobi.jl page, post the code you want to add, and we’ll walk you through the process.
