I'm actually on the side of adding all the traits (cpu flags) and
letting the operator make sure that their cloud is patched.
We don't want to make assumption on behalf of the user, if I am
$chip_manufacturer and I want to use OpenStack to do CI for regression
testing of these, then I don't have the ability to do it. The
solution of introducing a flag that says "it's okay if it's
vulnerable" opens a whole can of worms on a) keeping up to date with
all thee different vulnerabilities and b) potentially causing a lot of
upgrade surprises when all of a sudden the flag you relied on is now
all of a sudden a "banned" one.
I think we should empower our operators and let them decide what to do
with their clouds. These recent CPU vulnerabilities are very
'massive' in terms of "PR" so usually most people know about them.
