I'd imagine that for the vast majority (>99%) of users, it would stay exactly the same. You can download installers (a la any desktop/laptop) or go through a repo/store of your choice on Android and very, very few outside of tinkerers or techie types bother. Out of all my friends and family, I've yet to find a single other person with F-Droid installed or who downloaded an APK direct from a developer's website or github.
