I'll postpone worrying about the more general case until I meet it in real life. :)
That's what I thought, until I met it as a real life part of a PNG test suite. So now I'm considering postponing worrying about it until I meet a second such image... ;-)
I think we all agree that such imagery is weird, though, at the very least. It's not common, either. How did we actually arrive at the subject? Was I drifting off-topic, or did the original question include this case? If the latter is the case, I think we all agree best is to avoid writing such stuff, even if it could perhaps be possible in TIFF depending on your take on the Indexed tag, and it certainly is possible in PNG.
