I think React-Native should support the 16KB page size for the future.

Agree.
We haven't planned support for 16K page size in the near future as we're focused on rolling out the New Architecture.

To unblock yourself you can however:

1. Turn on build from source https://reactnative.dev/contributing/how-to-build-from-source
2. Bump the NDK to 27
3. Use the -DANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES=ON parameter as suggested in the guide (you'll have to patch.package also node_modules/react-native/ReactAndroid/build.gradle.kts to pass that config there as well).

I created the following repo where I use RN 0.74.3. (Repo)

1. Bumbed NDK to 27.0.11718014
2. Patched node_modules/react-native/ReactAndroid/build.gradle.ks
3. Created an Emulator supporting a 16KB page size
4. Build and launch from Android Studio Canary2024.1.2 Canary 5 as suggested here https://developer.android.com/guide/practices/page-sizes#16kb-emulator

As a result, I got the following exception after the app launched:
