CC 2025 v29.0 introduces the long-awaited "Scale Artwork with Artboard" option.

The checkbox in Preferences > Selection and Anchor Display > Move Locked and Hidden Artwork with Artboard now also affects whether locked or hidden objects are scaled with the artboard or not.

I didn't realize this right away. When I tried to scale an artboard with a locked object, I got a warning and thought that the new feature just doesn't know how to scale such objects with an artboard. Only then did I realize that the existing option in the settings affects the function.

Perhaps the naming of the option should be made clearer: Preferences > Selection and Anchor Display > Move or Scale Locked and Hidden Artwork with Artboard
