Just a simple observation to support that we should do this: requiring strict decrease of fnew in Bisection breaks two tests for BFGS and LBFGS. Permitting <= allows to get to a point with smaller gradient norm, so if we permit even a tiny increase, we could get closer to the minimizer for some problems.

We tried this, and it turned out to be a bad idea. We replaced this with the use of MajorIteration for the optimizer to control when stats get updated.
