The part in the flow where you select between allowing app installs for 7 days or forever is a glimpse into the future. That toggle shows the thought process that's going on at Google.

I can bet that a few versions down the line, the "Not recommended" option of allowing installs indefinitely will become so not recommended that they'll remove it outright. Then shrink the 7 day window to 3 days or less. Or only give users one allowed attempt at installing an app, after which it's another 24 hour waiting period for you. Then ask the user to verify themselves as a developer if they want to install whatever they want. Whatever helps them turn people away from alternatives and shrink the odds of someone dislodging their monopoly, they will do. Anything to drive people to Google Play only.

An actual example of this lives in the Gmail iOS app. Click a link in an email and every x days, a sheet appears: https://imgur.com/a/nlGS4Yk

1. Chrome

2. Google

3. Default browser app (w/unfamiliar generic logo)

They removed the option for Safari some time in the last two years; here's how it looked in 2024: https://imgur.com/1iBVFfc

And the cherry on top of dark UX patterns: an unchecked toggle rests at the bottom. "Ask me which app to use every time." You cannot stop getting these.
