Can a function that implements __Ownable_init by not with the initializable modifier be run more than once?
Yeah. That restriction is coming from a utility. There are options to modify the owner through transfer ownership on the `OwnableUpgradable` contract. You can also use the `reinitializer' modifier to create your own re-init logic.

Nuances of Using Upgradeable Smart Contracts
Most smart contracts developers have used Openzeppelin/contracts. Those developers dabbling in Upgradeable smart contracts use its sister project Openzeppelin/contracts-upgradeable. The two are the same albeit the constructor in the contract is replaced by the initializer.
