Possibly addressed with a different name. (Maybe something like 'make'? Do we have a consistent standard for the equivalent of an 'of' method, but with no parameters?)

The methods in Objects are conveniences that users could write themselves, which this basically is -- there's nothing special about this method, other than having a preferred alternative to `new Object()` which users will understand. So parking this where the Object conveniences go seems slightly lower friction.
Yes, Objects is a good backup option of we don't like the IdentityObject approach. With the added friction of "import java.util.Objects".
