I added one suggestion to the ticket <https://tm.tl/7097>: 
`warnings.showwarning(..., "", "")` will produce a message like ":: 
UserWarning: ..." (at least one the one version of Python I tested on, 
who knows if it's the same across all the versions we care about) which 
is still weird but less so.

Off the top of my head I don't have any better suggestions than that.  I 
guess there is the other obvious approach of just writing some bytes to 
stderr...

Considering my various experiences with the warnings module I'm even a 
little tempted to go that way.  It does seem like the choice is between 
really bad and only sort of bad, though.

(Oops, didn't click send fast enough, now I'm imagining other things 
like passing some other string to `showwarning` as the file name - like 
"Twisted TLS Support" or whatever else you want to make the resulting 
message look pretty.)
