Although I’m sure implementing this into a big codebase is a technical headache I hope this encourages other big Electron apps like Figma (or even Tana, a direct competitor) to support an offline mode of sorts.

This sounds like they’re trying to support cases where you temporarily lose connection while editing a document. Very different from being able to start up your computer without an internet connection, open a document you’d previously downloaded, edit it, and sync sometime later once you come back online (which is what Notion now supports).
