As you wrote. But software isn't just "secure" or "not secure",
all or nothing. Security, in any aspect of life, is gradational.

You don't expect people working at HQ to get shot or blown up,
but that is a more likely fate for those fighting at the front.
As well as variations with seniority and physical position,
there will be temporal variations, just like in civilian life,
1 through 5 or green through red etc.

Not a base; it's just inevitable, both in software and life.
You're increasing your attack surface as you install and use
more software, just like driving, visiting bars, attending
concerts, or going on foreign or adventure holidays.

I don't know about OpenBSD specifically, but in general it's
already done, by such methods as exposing software to malicious
and random inputs, corner cases, and so on. That doesn't have
to mean it's done /instead of/ auditing.
