Well, I'm not going to moan on about it, but the theory you describe for the next season was used to explain the longer wait from the previous season to the one that just finished. And, for some of us, it just wasn't better. I love the casting from the Doctor to the companions. But the stories were in general lacking strong villains, the Doctor was often an observer, etc. For me, it was the weakest season of nuWho. Easily. And, I enjoyed some of the episodes to be sure.
So, I'm not convinced that a longer gap will fix things. Although, on the other hand, I don't think huge changes are necessary. Less Chibnall scripts, stronger villains.
We'll see. The wait isn't that much longer so I'm not really that concerned myself.
