Why?
Picard S3 is Kurtzman too. You can't pick and choose which Kurtzman projects are prime timeline.
But kurtzman had little if nothing to do with it. Matalas seemed to be running the show on that one. But for it to work we would need all 3 seasons as canon unfortunately. But I can live with the first two even though they sucked really bad as long as 3 remains canon.
