I'm open to suggestions here. I've the API for the PortalLogic and its Builder to be a bit obtuse. The "composite" nature of what gets ultimately built makes it so as a consumer, I have to build a builder and then tell it to fallback to the appropriate portal logic depending on which type of portal I'm going through, even if I want to just override a single PortalLogic component. In what cases would you have more than two portals added to the rules set of SpongePortalLogicBuilder, potentially one for overridden functionality and the other as a fallback? And the fallback should be discoverable by the event depending on which type of portal kicked off the event.
