I've started ignoring .io domains, because they seem to be a convenient shorthand for "I care more about being trendy than being correct." I doubt this project is based in the British Indian Ocean Territory.
Was this comment necessary? No one cares what you think about the domain.
The comment is on point. The io TLD does seem to be used more for software which is trendy rather than which is useful, thus it makes a reasonable litmus test.
