in that case doing one method per command, then separating the "support level" on separate traits is maybe more idiomatic?

```rust
pub trait SomeTrait {
    fn do_command_one(&self) {...}
    fn do_command_two(&self) {...}
}

pub trait SomeTraitExtended: SomeTrait {
    fn do_command_three(&self) {...}
    fn do_command_four(&self) {...}
}
