The whole basis of an Alternate Minima verses the Landing Minima is to give us some options when the weather deteriorates at destination, ie. you'll have fuel to go somewhere else or hold.
Despite the ongoing debate and different interpretations of the law, what surprises me is the attitude of some (so called professional pilots), that continuing on into a situation of reported deteriorating weather, based on the assumption that it's above landing minima, we'll get in, is somewhat concerning!
