Well the benefit of having Java/Kotlin being the default dev language for Android is there's no need to recompile to run those apps on another arch. Only apps with native code will be an issue.
Where "only" means majority of games, especially anything created with common game frameworks, and non-trivial apps with native dependencies they pulled in.
"Multimedia" apps (anything image, video or audio-related, and even my e-book reader) are probably another large fraction (and since I don't have all that many separate game apps installed – mostly a few emulators only – they're actually the largest fraction of apps with native libraries on my phone).
