Depends what you want to define as a bug. What I am not happy about
is the prospect of random assertion failures for the next six months
while you finish redesigning half of the system. The rest of us
have work we want to get done, too. I don't object to the idea of
making no-lost-events an end goal, but we are clearly not ready
for that today.
