#rb Per.Larsson #rnx - Currently we apply filtering to payloads at two points, package save and during virtualization. The reasons applied during package save are stored int he payload trailer and are easy to access when making reports but we needed a way to find the second set of filters. - This set up is fairly hacky as we are accessing the default FVirtualizationManager directly, this is because I wanted to avoid making a public interface change as I am not 100% sure that we should be trying to fix filtering this way and am leaning towards either moving all filtering to a single point (both have their advantages and disadvantages) or making the difference between these two stages more explicit and for either solution I don't want to be tied to any interface changes we'd need to make here. - The new utilities header I added is internal so we can change it as we need, it is also marked as experimental so licensees should be avoiding it anyway.
