> some bugs you don't want to find

The key thing you forgot, which makes this approach non-sensible, is the omniscience, without which you have no clue whether your posture towards a new bug-finding tool is good or not, since you don't know whether it will mostly find those bugs that are not worth fixing and the time wasted on fixing them is detrimental.

Similarly, how is ignorance better than informed decision when ignorance also includes missing critical security bugs?
