Outputting a TV signal isn’t inherently a problem, surely? Every VCR and 1980s home computer has a circuit that does the same thing. Would only be an issue if you run it through an amp and antenna, rather than just running a wire to a TV, right?

Those sources are likely shielded and clean. A transmitter like this will radiate harmonics, and that's the major concern. It is not just a TV signal. All that said, this is nice work. Analog signals are a lot of fun. NTSC going away makes me sad. I have abused it to great results many times over the years.

  But doesn’t that concern about unshielded dirty signals apply to basically any use of a GPIO pin on a dev board?

    Yes and no. Depends on the frequencies, whether the pin is driving a load, and intended to radiate.
