Brendan - there is a lot of "tribal knowledge" that has been passed around those features over the years; generally speaking, our guidance now is that it is benificial to have those features turned on. I am aware of the fact that in many a support case in the past, support would guide you to disable the features and in depending on timeframe of the case, servie pack levels and drivers used - they were likely right to do so. We are working with support internally too, to help guide away from disabling the features in cases where there is no reason to do so anymore. The linked article really does represent the latest thoughts around it all.
