AFAIK, even a binary "canary" has been untested in court and might not even stand on its own (yet many companies have one).
There are countless loopholes in various legal systems across the world that "get a pass". It's often a matter of finding the right loopholes.
One example is gambling in Japan. Illegal. But if you play at a pachinko slot for a chance to win some tokens you can go next door and there is a business that will buy the tokens from you! It really is convenient someone is willing to buy these otherwise useless tokens. :)
I'm sure if I put some thought into it I could find a few more loopholes that are a "wink and a nod" away of being illegal. Of course, my suggestion might be too blatant and the company would be dragged to the courts. But even a single canary could still warrant being dragged to court over.
This is true, but there's a core fundamental issue. There has never been any legal support for the idea that the government can compel speech (such as forcing the continued false inclusion of a "binary" canary). There is a clear basis of support for the idea that the government can regulate speech, whether it's English or cryptic colored circles. So trying to speak (publish canary info) in any sort of cryptic way will still always be more risky than choosing not to speak (omit your canary). The government could always drag you to court over anything, but you still want to keep them at the downhill end of the battle.
