Looks good to me

Code wise everything looks good.

Can you provide me your example build command on how you tested it. How you set a single or multiple export options.

This information needs to be added later to the Cordova docs so others understand how to use it.

Not quite sure if this is what you mean, but I'm not using cordova through the cli.
So I didn't provide a way to set the exportOptions through the cli, but I guess it could be added as an option to the build.json.

I tested it through my build script that looks something like this

const build = async function ({ release, platforms }) {
    const exportOptions = { uploadSymbols: !release };
    const options = { release, device: release, exportOptions };
    await cordova.build({ verbose: !release, platforms, options });
};

build({ release: true, platforms: ['ios'] });

This will then not include the .symbols in the produced .ipa file.
This command should not print anything in that case (by default it does).

unzip -l platforms/ios/build/device/<app>.ipa | grep Symbols

Also as mentioned in the issue, right now the code does not allow to overwrite the defaults.
Not sure if that would be a good idea or if it would break the whole build. 😅

I hope this helps, let me know if I can help with anything else.
