Going to address this same request in a different way.
Accepting that exporting workouts isn’t going to happen, could you please look in to integrating with indieVelo? They allow for integration of workouts from a third party (currently intervals.icu and TrainingPeaks) directly in to the platform (so that your workout for that day is executable), which means that the end user has no access to the actual workout file. That means it works the same as outside workouts, and there is no risk to the TR IP.
This would be a win/win for TR and iV.
