Thanks for this background.

Based on your experience, we should probably ignore the IANA then,
and just declare a few useful "mime types" (note the quotes) in a
new BIP. We can then agree inside the Bitcoin community on their
usage and meaning.

Anyone want to write that BIP and shepherd it? I can support you
but I'd rather write code.
