I routinely get messages from ups.com that contain an HTML part all in
one line.

With "Content-Type: text/html; charset=UTF-8" and no
Content-Transfer-Encoding. Tens of thousands of bytes, which are UTF-8
code units.

My MTA spits a warning to the logs when a message comes in (via DATA,
not BDAT) containing a line >1000 bytes.

It's not very common, but I do see it. Most email I see nowadays is
Quoted-Printable.
