I'm pretty sure the page is supposed to be satirical. It's poking fun at the number of software projects that have been around for several years (or maybe even a couple of decades), have had dozens to hundreds of releases, and yet are somehow still at major version 0, which flies in the face of both semantic versioning and general common sense.
“One shall not speak of 1.0!” (Not an actual quote).
If 0ver works for your use case, go with it, by all means. It’s sortable (“nat-sortable” to be more precise) and it will get the job done. And so are many other versioning schemes.
Think about your release cadency, how will you release new versions, patches and fixes and then pick one that makes sense to both humans and your code.
