It’s true that you really, really want to avoid making changes to the engine. Even for AAA studio source licensees in prior UE generations this was widely agreed upon. The good news is, you really shouldn’t have to.
In my mind, the big win from having the Unreal source code is understandability. But also, in contrast to Unity, if you should for some reason need to—say a critical bug that’s stopping your game from shipping at the last hour—you at least have the option.
