Lack of double step transfer in admin modification in a upgradeable contract is dangerous. Admin is changed with changeAdmin that calls _changeAdmin, this is a 1 step transfer provided by ERC1967Proxy. If wrongly set to a malicious actor, contract can call upgradeTo or upgradeToAndCall and destroy the contract. Ownership can be lost, contract can be destroyed calling upgradeTo or upgradeToAndCall from UUPSUpgradeable
