I can confirm that isn't necessary. It shows up as a search result when I search for "github" on my iPad's App Store app right now.

I imagine the devs were wise enough to include "github" in the list of search keywords that you're allowed to attach to your App Store submission.

I'm talking about the search box on the SpringBoard (aka, the search box when you swipe left from the home screen).

That will allow people to search there for github and see the app in the list of launchable items.
