Setting up a game for patches and updates

Question

I read up on .pck files and their uses here, and it seems pretty straightforward for things like DLC or mods, but I'm a bit unclear on how this applies to things like patches and updates.

Say I make a game in Godot and there's a scene called "enemy.tscn" with a script attached called "enemy.gd", and it turns out there's a bug that needs some lines of code to fix. How would I create and apply a .pck file with the fix and apply it to the game? Is there some kind of workflow or setup required to make a game patch-friendly?

Thanks in advance!

To reduce patch download sizes, it's generally less effort to rely on binary diff systems provided by various platforms such as Steam. Just make sure to export to a PCK file instead of a ZIP archive (since compression will make binary diffs not work well).
