The "serp-categorization" ping is sent without the client_id, but if you look at its list of contained metrics it includes the default glean-core client_id uuid metric.
This could cause confusion.
(( For the record, I have confirmed that the client_id metric is absent on all pings with include_client_id: false so this is just an inconsistency in Glean Dictionary, not a data fault. ))
