That seems redundant. You can already turn off seeing retweets from accounts you follow, and the "latest tweets" timeline is already pretty sticky. I've never had it revert to the default "home" timeline across any computer or phone app install.
My experience has been about once a month the iOS app (phone & tablet) will revert from Latest to Top. It will show an easy-to-miss toast message saying "You're now seeing top tweets first."
Once a month sounds nice. Mine likes to revert within a week :) (for the times I actually use twitter more than a couple times a month)
