The `security_attributes` function is marked as safe despite taking a raw pointer which will later be used. Fortunately this function is only used internally and only in one place that has been basically the same for a decade now. However, we only ever set one bool so it's easy enough to replace with something that's actually safe.

I spent some time wandering through other reviews and... interesting observation: people really don't like bool flags around here - readability issues, they say, I've been switching to enums myself, even for simple true/false cases

I think this is much more relevant for function parameters, but this is mostly a struct field and so it's less relevant (I'd even argue marginally harmful).

I'd just note that OpenOptions uses bool for most parameters. If this were a public API then we'd likely want to be consistent with those existing methods anyway.

Fortunately this function is only used internally and only in one place that has been basically the same for a decade now.

But that should be properly designed (and safe!).
