If you let someone else have the glory, you'll still be the creator of the npub/nsec format, which will be remembered as one of those "so this is what it took a really smart human to first notice it was a good idea at the time" like other great inventions in history. You can pretty much work on whatever you feel like for the rest of your life with no regard to your legacy. However, if your version of github is the one that eats github, you will also go down in history for that. Something to think about.
