I think this is a good feature to support, but I'm a little worried that this implementation is a little more complicated than it has to be. The syntax seems good for users, but the implementation feels a little hard to reason around because there are so many methods with the same name and, in my opinion, some methods are in odd places.

The usage of the functional interface allows for keeping a dynamic calling, and also exactly as you said. There are very similar methods with similar parameters which is the exact purpose of a functional interface.

This can easily be expanded apon to add support for TeleportCauseEvent if and when needed, as there are also those methods in the Entity class.
