Has fire worship been implemented as an ideology yet, or has Tynan made comment?

Hi 
 
Having made lots of lots of personal roleplaying colonies based on fire worshippers led by a pyromancer. I was super excited for ideology since a fire worshipping cult sounded like a given. Unfortunately it wasn't added. I was hoping something like pyromancer will light holy braziers instead of random fire sprees, sacrificing prisoners by burning them, unique flame weapon or gear etc. 
 
Has this been implemented in some way? If not, have Tynan mentioned the possibility or confirmed/denied if it will happen or not? Just wondering if I can be hopeful, or if I shouldn't get my hopes up.
