Hardly the point though. For us this is a bother at most, but we can cope because we're already doing our own thing and know what we want. Imagine trying to get your non tech-savvy friends to "sideload" (install) an app from outside the Play Store. Right now it's not a big deal, so if they're interested in the app, they'll likely install it. But this amount of friction and scary warnings is way more likely to stop them.
