My answer will have to be "yes, for now". When I started making my homebrew, I was still quite new at D&D and found I had enough work ahead of me without coming up with a pantheon as well. The ones that have featured most heavily are Nerull, Erythnul, Pelor, Heironeous and Moradin.
I always meant to make my own some day, and it's happening right now. A longrunning campaign has reached so far into epic levels, it's time to plan its ending. I'm letting it go out with a bang; an all-out war between the good and evil deities. I plan to eradicate 99% of the pantheon and parts of the material plane, giving me the chance to create new gods and rearrange everything I'm not quite happy about on my homebrew world. My current PCs will become part of the pantheon, but there will also be several of my own creation.
