How Religion Works?

I have no idea if any of this has been said already but what is up with religions in AoC2, not in game since there is no religion feature in it although if you search through the files you can easily see that religions may have been planned to be implemented for example image files in the UI or the religions folder in 'game, my question is if they were going to be implemented like it appears they were planned to what stopped them from being implemented? And maybe if the stars align and the impossible but long awaited update begins development may they become a feature?

I saw that this game has religions, but i don´t know how does it work.

Lukasz said in steam that he works on something who know maybe its religions or nuclear bomb?
