At least with keepassDX on android there is no internet access permission needed by default, but if a compromised update suddenly required it I don't know if Android would prompt about it since all apps have internet access granted without prompting :(
I also wish it was possible to block automatic updates of specific apps on the play store... So at least we could be in control over updating critical apps such as these without having to micromanage updates for all apps.
On GrapheneOS there is a prompt when installing an app that asks if you would like to grant network access. I am not sure if that pop up displays if network access is added later in an app update though.

yes, it's my biggest worry too.

I'm pretty sure I got prompted once or twice before updating to app with new permissions added.
