This pattern implies two * things that go hand in hand: * * 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if * that call matches the {ITransparentUpgradeableProxy-upgradeToAndCall} function exposed by the proxy itself. * 2. If the admin calls the proxy, it can call the `upgradeToAndCall` function but any other call won't be forwarded to * the implementation. If the admin tries to call a function on the implementation it will fail with an error indicating * the proxy admin cannot fallback to the target implementation. * * These properties mean that the admin account can only be used for upgrading the proxy, so it's best if it's a * dedicated account that is not used for anything else.

However, the admin slot defined in ERC-1967 can still be * overwritten by the implementation logic pointed to by this proxy. In such cases, the contract may end up in an * undesirable state where the admin slot is different from the actual admin. * * WARNING: It is not recommended to extend this contract to add additional external functions.
