My confusion mainly came from the below blog post. It indicated that as from 2017, an app would not have product updates applied when new versions of the client are released. My conservative reading was that this would mean that an app was using the old client until it's published again.
Now I understand that I was misreading the blogpost. Before, they were updating actual app logic. As from 2017, they stopped doing that, meaning your app can theoretically break at any point in time if the client would be updated. I also understand that the "Power Apps release" column in de "App details" section is just FYI, and does not indicate the actual client version the app is running in. The client is always up-to-date.
This makes the six-month-republish-requirement a best practice, and not a security necessity. Updated my own thread just in case someone would find it at a later point in time.
