As a consequence we can also get rid of some `dynamic_casts`, so the diff may be a bit harder to understand at some points.\r\nNote that the `clone()` call will be simplified by #12949.\r\n\r\nTesting:\r\nNo new tests were added, since there is no new functionality. In principle our existing system tests should cover this.\r\nOne idea for testing manually: Apply algorithm to an event workspace, and see if both in-place (input == output) and not-in-place still work as expected.\r\n\r\nNo release
