I disagree. In my opinion it is better to get just something that is a step away from previous problems. No need to get anything very slick. I am hooked at waiting the next episode after the cliffhanger we got last Friday:
Without testnet it would feel like moving back to the “no timelines” zone. Well, of course there are not timelines at the moment, too, but you know what I mean.
But this is just my opinion, and it is not about the actual technical development, it’s just about what kind of narrative would feel better. Cliffhangers should be resolved soon enough 
And I am confident they will.
