The recent European regulations do not have aopp like requirements, but it seems inevitable from the tone of this legislation they will. Individual countries may also decide to interpret it in a way similar to the Swiss if you withdraw to self custody. We should not make it easy to "over comply" by signing to prove control of our self custodial addresses. If they want to make that a requirement they can implement it and users should have an appropriate amount of fear/resistance for using such systems.
