A development model in which nothing ever changed would introduce no new
bugs. The current development model has a high change rate.

The remainder follows by induction.

(Not that it's very *useful*, but when was the last time you heard of a
bug of any kind being introduced into TOPS-20, or DOS?)

Development model

So true. And with the current rate of changes, any statistics are less than useful: the last development cycle may have produced some 170k new lines and maybe 20 vulnerabilities. That is one CVE per 8k lines of code, i.e. a needle in a haystack.

A really useful study on vulnerabilities would have to contemplate (as our editor suggests) the rate of changes, the rate of introduction and the rate of removal; and compare with other development models. Anything else is just anecdotal evidence.
