I was worried that this meant that we'd have to change all our tests to use some other mocking mechanism, but discussion at https://github.com/sebastianbergmann/phpunit-mock-objects/issues/425 suggests that the functionality was merged into PHPUnit in 7.x. So the functionality should still be there, just without needing to pull in this package.
