Stuffing vs Dynamic feature modules

[TorkelV]

Why would you use Stuffing instead of native dynamic feature modules? Did you try using them before writing Stuffing? https://developer.android.com/guide/app-bundle/dynamic-delivery#modularize

I am wondering what this solves that can't already be done with dynamic features.

Couldn't you add both apps as on-demand feature modules, and decide in the base module which app to install? Or include one module and later install the other one? Then you could uninstall the first included one if you wanted. Wouldn't that reduce the apk size even more? And you could easily share resources from the base module.
