[Ipopt] Feasible iterations only - again

In my current model, the objective is only defined for a feasible 
design. Hence the nonlinear inequalitiy constraints
need to be feasible for the nonconvex nonlinear problem.

If found an old thread: "Feasible iterations only" 
Here Andreas states that this is not in Ipopt and not planned.

I have not much hope, but anyway - has this changed meanwhile? Anyone 
knows a solver with this feature? E.g. SNOPT, KNITRO?
