iOS Password Auto-fill vs App Extension

This help article states:

There are two settings which need to be enabled on iOS to cover all Auto-fill scenarios, Password Auto-fill and App Extension.

However, in my (very limited) testing iOS’ native Auto-fill works for both Safari web pages and apps. I also prefer its interface over “sharing to the app extension”. Is there any reason I would want to leave the Bitwarden extension enabled? I.e. does the Bitwarden extension give me features that iOS AutoFill doesn’t have?
