False `DeprecatedMethod` positives for `expects`

[leighman]

Not sure if this is a psalm issue but thought I'd come here to clarify how stubs work.
Using PHPUnit 7 which has

    /**
     * Registers a new expectation in the mock object and returns the match
     * object which can be infused with further details.
     *
     * @return InvocationMocker
     */
    public function expects(Invocation $matcher);

in MockObject.
This doesn't seem to appear in the stub but no error in IDE (possibly because psalm warning level is not high enough?)

When calling createMock(MyClass::class) and deprecating __call on MyClass, I get errors about DeprecatedMethod for uses of expects.
Is that expected behaviour or is something incorrect?
