Resolution Note (2022.1.X):
Prior to 2021.2, when bones where imported which were not bound to vertices the Model Importer stripped them. This made the generation of reusable rigs more challenging.
From 2021.2 onwards a new flag was added to the Model Importer to enable/disable stripping. For existing assets it's enabled by default (preserving the existing functionality), but for new assets it's disabled. In this case, enabling the "OptimizeBones" flag on the Model Importer returns it to the existing functionality.
