In the normal KiCad gerber export, there is an option which is enabled by default called "Check zone fills before plotting".
This will show a popup if you've modified the board, but forgot to re-fill zones, and prompt you to update the zones.
However, there is no such option or check for this plugin.
This would be useful in preventing PCB errors due to forgetting to re-build copper planes.
I'm not sure whether this is currently possible within a KiCad plugin. Also, not sure if there is some other plugin (like KiKit) which already has this function so you can use it as reference if you decide to implement it.
