KYC/AML for cross-border EU equity trading

Anyone else finding the differing KYC/AML requirements across various EU jurisdictions to be a real drag on operational efficiency for retail brokers handling cross-border equity trades? The fragmented regulatory landscape seems to be creating more friction than it solves, particularly when dealing with smaller ticket sizes. Are we seeing any movement towards greater harmonization, or is this just the price of doing business in Europe for the foreseeable future?
