No, the whole point of using an alternative app store is to get better deals for developers or end users. Apps that are not approved by Google can still be installed. The whole point of app verification is to allow installation outside a system app store (e.g., directly from a website or from another app store) without any scary warnings, as required by the judge's ruling.
All Google Android builds show a scary warning before you can install apps outside the system app stores. That's why the judge's ruling required Google to do away with the scary warning, leading to app verification, which accomplishes what the judge required. If you don't use a Google Android build, neither app verification nor the new unknown source installation flow affect you.
Instead, as I pointed out in my original comment, we need to complain about the upcoming "advanced flow" for unknown source app installation. It should not but does require enabling developer mode. It should and does save the user's preferences for unknown source installation across device updates.
