I agree with @TobiasF but also like @Johannes’ idea and understand @Hecki and @StephanK.
It would be great to have an openOS working almost like the GMS one, i.e. with basic apps and nothing extra to be done for a working GPS. But you can’t force someone to use an app rather than another.
Maybe a good compromise (but I don’t know about feasibility) would be to use to updater to install a “pure” OS and then give different options:
- Exit the updater app to configure the phone by oneself
- install an app-store
If one chooses option 2, after the installation of F-droid, 2 choices:
- exit
- install other apps
- 2a) choose a package (one or many options of some of the basic apps, as for OpenGAPPS)
- 2b) customize the installation:
- 2b.1: choose a browser (amongst some choices or option to display all current choices on F-droid)
- 2b.2: choose an email client
- 2b.3: choose a music player
- etc. (with the option to skip what you don’t need/want)
It would be great, but it looks complicated…
