guardian is mentioned as an area of concern in the docs:
guardian is a roll that has the ability to pause and unpause TemporalGovernor. In code, it uses the owner from OpenZeppelin Ownable as guardian. The issue is that Ownable::transferOwnership is not overridden. Only guardian (owner) can transfer the role.
This can be a conflict of interest if there is a falling out between governance and the guardian. If the guardian doesnt want to abstain, governance only option would be to call revokeGuardian which sets owner to address(0). This permanently removes the ability to pause the contract which can be undesirable.
Simple test in  TemporalGovernorExec.t.sol:
Consider overriding transferOwnership and either limit it to only governance (msg.sender == address(this)) or both guardian and governance.
