The main advantage of JWT, at least the advertisement historically, has been they are stateless and scalable, but that black list makes the system stateful again and you loose out on most(or all scalability) benefits. I think how much you loose depends on the specifics of the implementation, you definitely seem to loose any simplicity of design though from what I have read/worked with.
