The discrepancy between the NatSpec comment in the _addOwner function of the MultiOwnable contract and its actual implementation could lead to misunderstandings about the contracts owner limit. The comment suggests a limit of 255 owners:

But the code, utilizing uint256 for indexing, does not enforce any such limit, allowing for a significantly larger number of owners.

This issue, while not affecting the contracts functionality or security directly, could cause confusion among developers and users, leading to potential misalignments in expectations and implementations. Addressing this through clarification in the documentation or by introducing an explicit limit, if desired, is recommended to ensure clear and accurate communication of the contracts capabilities.
