b) custom viewHelper fetching addon objects
One workaround would be to use "addon objects" and assign those to your
view using a custom viewHelper that fetches the related "addon object" from
a repository. While this works fine to just render the related properties,
it'll be a bit more work on the controller side if you like to make use of
FE editing of the foreign extension (you would need to override the default
controller with a custom/extended version using DI)

how do you relate this addon objects in the TYPO3 backend? can the
properties be editable right within the form of the original object?

kind regards.
