FWIW, I agree completely with everything you said, and I hope it's reflected
in what I wrote.

NYT? Wow. I hadn't noticed they were one of the places that does it. The
example I usually think of is one of the sources of political spam^H^H^H^H
legitimate bulk mail which seems to do it intermittently. But that's
nowhere near as good as example as the NYT.

Another amusing thing one of these bulk email generators does is put out
multiparts marked with a quoted-printable CTE. (The multipart is not, in fact
encoded, although there have been other cases in the past where it was.) I
don't know if this one is worth calling out in the doc or not.
