His role in the plot has essentially wound down. There's just no time to focus on his schemes with everything else also going on without making the show even longer, one of the benefits of the books is there's much more space to fit in additional branching storylines it's the same reason there's no Lady Stoneheart or Aegon or why Sansa usurped Jeyne Poole's plotline.

And frankly I guarantee Sansa is going to be his death in the books as well.
