I get the feeling that might be another reason why they delayed the Bad Batch and released Tale of the Jedi instead. One, it gives us context to Dooku for when we see his old palace and how hypocritical he became with his War Chest, but also to set up Ahsoka being in Bail's Rebel service after roughly a year in hiding.
That one bugged me a bit, since it was basically retelling the events of the novel Ahsoka but in a way that conflicted with the specifics. Which belies the whole "everything is canon" notion, and besides, I liked that novel.
I found Tales underwhelming overall. The Dooku segments were fine, but too short. That story arc deserved a whole animated movie, maybe. I suppose maybe much of Dooku's backstory was already told in the books, but as the final Ahsoka episode showed, they're willing to overwrite the books.
