I know it's easy to be like "wow LEGO isn't acknowledging Bionicle at all, they don't care anymore" but like... Actually think about it for a second from LEGOs perspective. Bionicle is a theme that they haven't made sets for in almost 5 years now, and the last sets sold so poorly, the final wave was delegated as a "Toys R Us 'Exclusive'". So Bionicle has a relatively limited appeal currently. Plus that set would require quite a bit of knowledge on older Bionicle stuff so you're seriously limiting the number of people who would be remotely interested. Most people would look at it and be like "oh robots. That's weird" and move on to something else.
Plus LEGO likes making little references to older themes, but they never just release tribute sets for themes years after they've discontinued (technically they did for Classic Space, but those were just made because of the LEGO Movie having a hard-on for Classic Space).
Bionicle had no chance, unfortunately. It would have been awkward to acknowledge a theme that ended so poorly, and a hard sell to the vast majority of the LEGO buying crowd.
