Discord isn't scrapping its plans, just assuring people that one of the vendors they trialed in a sub-market they aren't moving forward with globally. They've been trying for a multi-vendor solution from the beginning and k-ID is the vendor they've been much more publicly happy with than Persona.

Today Discord also released a rather comprehensive (and good) recap of the plan so far, their apologies for some of their messaging mistakes, and what comes next: https://discord.com/blog/getting-global-age-assurance-right-...

(Also, from that post most notably mentioned about the global rollout is delayed in light of some of these vendor verification issues and also hoping to rollout a few more features to even further lesson the need for age verification by many users. One such feature being first-class opt-in "spoiler channels", which some servers had been using age restricted channels for that rather than opt-in roles and somewhat more complex role-based permissions.)
