#UpgradeNotes:
The TStructOpsTypeTraits<>::WithMessaging type trait is no longer necessary for UStructs intended to be used as messages, because UObject creation and destruction is now thread-safe, and message types no longer need to be pre-cached. You can now use any existing and custom UStruct class in the Engine as messages. I ran the Editor for a couple hours with the profiler enabled and did not have any stability issues. If you experience any Messaging related crashes, please let me know asap, thanks!
