While we don't want to aim for the shortest list of disabled features in the baseline result (it would select a very old model), we want to do so while looking at any of the input models for which we're trying to compute a baseline CPU model. Given a set of input models, we always want to take the least capable one of them (i.e., the one with shortest list of disabled features) or a better model which is not one of the input models. So when considering an input model, we just check whether its list of disabled features is shorter than the currently best one. When looking at other models we check both enabled and disabled features while penalizing disabled features as implemented by the previous patch.
