F-Droid can generate one build per architecture, done for quite some apps like Element for example. Build scripts need to be modified a bit if you want that but it is possible

Note that splitting apk into different ABIs will complicate offline redistribution of the apk in cases of disasters or political protests/internet blockages.

Isn't this already enabled in 1e6c69f69e/android/app/build.gradle (L269-L276) but F-Droid picks up the universal APK and could pickup per ABi instead?

One note is that, we need per ABI versionCode, usually done via something like


    android.applicationVariants.configureEach { variant ->
        variant.outputs.each { output ->
            def baseAbiVersionCode = project.ext.abiCodes.get(output.getFilter(com.android.build.OutputFile.ABI))
            if (baseAbiVersionCode != null) {
                output.versionCodeOverride = (100 * project.android.defaultConfig.versionCode) + baseAbiVersionCode
            } else {
                output.versionCodeOverride = 100 * project.android.defaultConfig.versionCode
            }
        }

    }

Hence for universal versionCode 23122004 you end up with 2312200401 for armv7, 2312200402 for arm64, ...etc
