About that naming:
All Cairo instructions/ builtins have a corresponding component.
There are also components that are not related to an instruction (e.g. blake_round component)

WDYT about vm_components?

        import_from_vm_output(args.pub_json.as_path(), args.priv_json.as_path())?;

    let component_counts = vm_output.components_usage.counts();

Re my comment above, this won't contain all the components.

Code quote:

let component_counts = vm_output.components_usage.counts();

/// no ap++ (0=false). Note: for the flag "fp/ap", true means fp-based and false means ap-based.
#[derive(Debug, Default)]
pub struct ComponentsUsage {

WDYT?
I don't think the word usage fits here well

Suggestion:

pub struct VMComponents
