Optics Compatibility with System Hosts File

[athyfr]

I think that with compatibility features, Optics could be utilized a lot more.

One feature that I haven't seen in other search engines (including big ones, like Google) is to do a connection check to websites in the results, and filter them out if they are DNS blocked. (inaccessible)

This would significantly improve convenience for those using these systems, and could be completely optional.

Could something like this be implemented in Optics, or is it already possible?

EDIT:

Maybe this could be something like:

Rule {
    Matches {
        CanConnect(false)
    },
    Action(Discard)
};
