Millions of years of biology have brought us nearly to the point where we can take the evolution of our species into our own hands. We're new at this and like any other human endeavor in its earliest days are bound to make some horrible mistakes. So the arguments toward caution are well-justified. We've yet to prove our civilization is responsible enough to handle such consequential abilities - e.g. nuclear arms, climate change, genetic engineering. But I anticipate several generations from now, today's cultural taboo will be ancient history and our "meddling", "treatments", whatever you label it will be just another aspect of humanity that has been normalized. I bet my progeny will be able to go and get a tail just as easily as someone today would acquire a tattoo.
