Thoughts on cross-border CFD regulatory divergence and client onboarding?

Been thinking a lot about the increasing divergence in CFD regulations across different jurisdictions, especially when it comes to client onboarding and ongoing compliance. For firms operating globally, navigating these varying KYC/AML requirements, suitability assessments, and even product restriction differences (e.g., leverage limits, binary options bans) is becoming a real headache. How are others managing the operational overhead and risk of onboarding clients from multiple regions without building bespoke systems for each one? Specifically, I'm curious about practical strategies for harmonizing parts of the process while still adhering to the strictest local mandates. Any tips on managing the 'lowest common denominator' approach vs. tailored pathways, particularly concerning the constant evolution of these rules?
