Apart from that, I don't really understand the urgency of riding big
horses at the speed of light reporting an RC bug against part of our
architecture only because an (sorry for being rude) obscure proof of
concept just got unveiled.

I don't think that ringing the trumpets of Apocalypse is exactly the
best way to work on the issue.

Please call me wrong as long as you want but I'd really like to see
people I trust in this project bring some advice on that issue.
