And the out-of-universe explanation is that we can recognize Changelings on site. If they didn't do it, they would have to tell us each time we ran into a Changeling. This was just easier.
To me, Star Trek's stories are about the depth and complexity of human relationships. It studies us and asks us to look within ourselves, to relate, to ask how would we respond to all that is in their world?
