hemlockiv [how] helpful is it if there's only like ten of those other apps in total?
The Accrescent devs are deliberately limiting the number of apps while they build a scalable infrastructure, and add the features expected of an app store. They obviously expect to have far more apps in the future.
hemlockiv Why not have F-Droid in the Graphene App Store?
1) F-Droid signs most apps themselves, so you are trusting them in addition to the app developers
2) F-Droid has a history of sketchy behavior
I do not speak for the GrapheneOS team, but based on past comments, I think they would discourage people from using F-Droid for apps that can be obtained from elsewhere.
