Web attackers do not need to know how to write stack overflows, Dave.
If you can code, you don't even need to know how to write stack
overflows to pen-test shrink wrap software.

Two observations, which I can make because our team can obviously
throw down the archaic exploit writing skills:

- In the commercial market, the ability to find vulnerabilities
commands a far higher price than the ability to write exploits. This
isn't opinion; it's simply empirical. People who actually write
exploits all day tend to work for vendors. A majority of consultants
can't.

- Most of the game-over vulnerabilities we find aren't code injection
anymore. You're proposing a metric that could fail someone who can do
DH parameter tampering, because they don't know the X86 Windows system
call gate.
