Apart from what's already been said: I am not aware of any god that's been made (design or code) by a single person. It's always been a group effort.
For example, I suggested an Abyss god (with powers to leave and enter the Abyss), and it was considered a good idea. Then it was discussed and the other powers were suggested.
The core idea for the slime god (you get piety from fellow jellies slurping items) was suggested by Cyrus (I think) in an ancient Sourceforge FR. That idea is so cute that it was carried around (on the dev wiki!) and got into the game when we made it an Implementable on Mantis (actually implemented thanks to 78291, who kept caring for Jiyva ever since).
Bottom line: never expect a GDD proposal to become a god, especially not as-is. If you get positive feedback, consider tweaking your design. If your god ever wants to have a chance being implemented, make a dev wiki page.
