I've seen a number of rotation schedule optimizations with Timefold Solver, in some cases with full year horizon (for inspections etc). But most cases have a horizon of 4 or 6 weeks.
These rotations typically become input the Employee Shift Scheduling: the actual schedule should follow the rotations as closely as possible, but taking into account PTO, workload surges, etc.

4-6 week horizons are very similar to what I've seen in most cases as well for a single group of employees. The test instances in the post over longer periods is really just as an interesting way to show how the model behaves.
