That new "Implicit check for Unity object lifetime" is nonsense

[aybe]

Just noticed that new suggestion after upgrading today.

See by yourself, code was fine but applying either fix makes it worse actually:

First fix is valid. Casting UnityEngine.Object to bool is essentially a null-check, but shorter. Reference

So, in this case, Visual Studio's warning about null-dereferencing is invalid.

The second fix modifies code behavior by only checking the reference for null, ignoring the UnityEngine.Object lifetime.

Both context actions are applicable.
