That's true but it's important to not underestimate that importance of defaults. Not only because it's more accessible out of the box, the ecosystem then can rely on it which means that crates you encounter are more likely to integrate nicely with whatever you're doing. Integration with the stdlib can then also be richer vs as a standalone crate. A great example of this is temporary file management. It's silly that's not bundled in the standard library. That being said, I'm responding to the general philosophy. I haven't looked at anything in this specific crate.
