So right now I think the answer is still no we can't uncap it.  To the best of
my knowledge monasca still suffers a substatial performance decrease and the
switch from sync to async producers isn't desired for them.

Unfortunately this comes down to monasca and olso.messaging getting on the same
page with python-kafka.  From a requirements POV we really only care about
co-installability, which uncappiugn clearly breaks.

Yours Tony.
