1. The wording here is really off. We don't really recommend this highly.
2. This is even contraproductive as it disallows updating via the app store
3. Once we have automatic updates this will effectively decrease security from my PoV
Also, an attacker can execute code also using other ways once they have write access to Nextcloud or the data folder.
