Not really. I have a gesture programmed in Nova Launcher to disable biometrics with a pinch. The system allows you to do many more things than iOS, just not put of the box.
The original statement was

A custom-made gesture using a third-party launcher is not built-in (to say nothing of whether that's accessible or feasible for the vast majority of Android users).
Most users would be okay with having these features only available through the Apple App Store.
Instead, the result is none of those features on their phone.
