I wouldn't like it but I can see it happening. It is more likely to come
from security companies that fund alot of research into vulndev and they
consider their sigs to be company secrets. Think about the last
marketing pitch for IDSes you have been through, "we detect far more
attacks than anybody else." You don't have the same punch when your
marketing is "we detect everything everybody else does."
