That sounds less than ideal. reparent() proably does what you want. Or
you could just choose not use manage().

I don't think that there is a clear way to remove a manage()ed widget
from a container without destroying it.

I guess remove() should not destroy the widgtet in C++, and you should
probably add a bug about that. But then who would destroy it? You'd need
to be sure to add it to something else, or unmanage it.
