It was already discussed in [How does ModelingToolkit use bounds metadata? - #6 by ChrisRackauckas](https://discourse.julialang.org/t/how-does-modelingtoolkit-use-bounds-metadata/81487/6)  
And I opened an issue based on @ChrisRackauckas reply here [Consider supporting bounds for `NonlinearProblem` resolution · Issue #183 · SciML/NonlinearSolve.jl · GitHub](https://github.com/SciML/NonlinearSolve.jl/issues/183)
