As I mentioned in the other thread, in my mind IterationType is about the upcoming function evaluation. It should return a type. For example, NelderMead may need to construct its initial simplex. The first function evaluation is not the start of a MajorEvaluation, but instead an InitialIteration or something.

As I replied in the other thread, IterationType being about the upcoming function evaluation is natural and consistent with EvaluationType. In that case, Linesearch.Init() must be fixed to return MinorIteration, not MajorIteration as it does now.
I will close this and submit a new issue for fixing it.
