Arguably, Apple already offers a version of a “pre-load” button in Safari (on iOS and macOS), with the setting to “Automatically save Reading List articles for offline reading”. (Not on by default, but the user sees a prompt to turn it on the first time they add an article to the Reading List.)

Ideally, you could add an article to the Reading List on your computer, and then view it later on your phone that downloaded it in the background when it still had network access.

In practice, my quick testing results just now were mixed: Safari kept saying that a Medium article wasn’t available offline, a Quartz article only loaded the header (with what looked like a fully-opaque white overlay covering the content itself), but a Daring Fireball post (i.e., without any JavaScript trickery) loaded just fine.
