Description
The summary for the generic version of CompareExchange<T> states: "Compares two instances of the specified reference type T for reference equality..." but that is no longer true as of .NET 9. Specifically, the class constraint was removed in .NET 9 so that a reference to a primitive value type (like bool/enum) can be passed into the method. See dotnet/runtime#104558 for the pull request where the change was made.
Exchange<T> was also changed as part of the same pull request, but the documentation only says "a variable of the specified type" and doesn't mention reference types so it's presumably correct.
