That's precisely what I meant by "whether it ever gets implemented is up to policymakers." The central banks, though, are the ones who actually implement the mechanics of the CBDC, even though policymakers are the ones who authorize it. And it's likely that unless policymakers are especially wonkish about those implementation details, they will defer to the central bank's research and recommendations, in terms of how it should be implemented, once the policymakers have decided that they want the central bank to introduce a CBDC.
