Yes, like that.
The Owner thing can be viewed (very, very basically) as just a gimmick to let you forget to free/destroy components: the Owner takes that responsibilty on its own, which is nice for long-lived objects inside "container" controls (forms, frame, panels, etc.).
But that means that you should really
forget releasing them on your own, so if you want to do that (control the whole life-cycle of a component) then you should assign no Owner to it.
It shouldn't matter much, since a possible Owner should be programed in such way so at to recognize when an owned component is no longer there. Of course, "should" doesn't mean all of them "do" it, so better safe than sorry
