Cross-border DeFi KYC standards - any movement?

Seeing continued chatter about decentralized finance and KYC/AML. What's the general sentiment on a unified or even harmonized approach for KYC/KYB across different jurisdictions for dApps? Seems like a bottleneck for institutional adoption, especially given the varying interpretations of 'custody' and 'control' in the space. Is anyone seeing any concrete regulatory proposals or discussions gaining traction?
