Gruumsh might be a little specific but consider that orcs worship a god opposed to gnolls worshipping a demon lord and other races perhaps worshipping an archdevil. The names are irrelevant but the details influence the story of the races. No matter how cruel and savage orcs might be, they still have a sense of organized religion and faith in a higher being, opposed to gnolls who venerate a chaotic beast of supreme destruction.
Thats exactly what I don't need. The specific names and details of this power or that background element, you never know, I might use them. The basic concepts of the creatures, which predate any deistic links and is still largely independent of it, that I want. But turning originally obscure bits of background into some sociological theory that's supposed to really differentiate the races, no thanks.
