No because the average user doesn’t know they care. They’ll just blindly install whatever and I lose the protection and safety that Apple provide.

For Android, this is how I would approach it if I had to do it starting now:

Add a checkbox to show apps tjat aren't approved yet.

Make it default off. Turn it off every time you leave the Play store app.

Disable it for people under 18.

If a user still wants to install the app point out the app isn't approved yet and ask for password.

There, problem solved..?

It'll got the same route as grandma installing malware. It doesn't matter if credentials are needed unless it creates a real barrier.

On macOS the vast majority of users still install apps outside the Mac App Store and this hasn't really been a problem.
