I only ever see those types of lids for home canning, and they tend to be single use. I’d wager they also are non-trivial to align during automated production and that’s one reason they don’t get used commercially (probably also just more expensive to have a 2-part lid). Also while they can be easier to remove the first time a jar is opened, I think it’s a significantly worse UX every time after.
