Should "unused" directives cause blocking errors?

[abathur]

I'm not sure whether it would be simple or painful to implement (so I don't want to frame this as something that will happen, or will happen rapidly), but I've idly wondered a little if resholve should error if an issued directive never does anything.

A more concrete example might be an invocation that says resholve should allow /a/specific/absolute/path--should resholve error out if it never encounters the path?

I can imagine this catching some misunderstandings and helping clean up vestigial directives, but I probably won't prioritize it until/unless there's obviously demand.
