Will F-Droid add specific support for arm64-v8a etc?

This is controlled by package versionCode

F-Droid’s logic is like this:

• device advertises support for some arches
• F-Droid installs the highest versionCode package that is compatible

Eg. You can have 3 packages

• universal armv7+v8+x86+x86_64 versionCode 1
• armv7 versionCode 2
• armv8 versionCode 3

If device advertises armv7 it gets 2

If device advertises armv7&armv8 it gets 3

If device advertises armv8 it gets 3

If device has x86 or x86_64 or both, it gets 1

So having universal too is not an issue, as we guide devs to set a proper versionCode
