@badboy & @chutten, when I ran tests locally with glean_parser v19.0 there were failures related to your mozilla/glean_parser#776 and mozilla/glean_parser#784 PRs, respectively. I've added the associated new properties to the CommonPingData interface, but don't have enough context with this codebase to know if anything additional needs to be done.
