Yes, but it has never been part of iOS 6, and still looks the same on iOS 7. It's not even a major app - the current version has half the reviews of Pages, which costs $10, and roughly a tenth of the reviews of the Podcasts app, which mostly duplicates functionality found in the iOS 6 Music app. I'm not sure if there is any metric by which FMF is a major app.

It looks the same on iOS 7 because Apple hasn't updated any of their non-preloaded apps yet. (iTunes Connect, Apple Store, iTunes U, Podcasts, iBooks are all other examples which have not been updated)

Given that FMF made it into the keynote both when it was introduced, and yesterday, I'd say it's important to them. (Not just text on a slide)

Edit: Whoops, I was thinking about Find My iPhone from the keynote yesterday, my bad. It was introduced in a keynote before.
