Lets take another look at this argument against high cardinality.
Why are we so set against it? What is the problem with having
100 entries for default passwords? By all accounts the CVE will 
have more than a thousand entries in the near future with or without
the high cardinality entries. So what is the point of trying to
stop high cardinality entries for entering the CVE? Either way
how many default passwords are there? 100? 200? Is that high cardinality?
Not sure we would all agree.
