The legislative change issue is an unusual example of vendor lock in. I wonder how much of EU law needs to be done through regulation instead of directives. When it is done through directives it forces governments to pass the legislation so the cost of implementing legislation so the laws don't blow up if you separate from the EU is lower. I guess directives over regulation might not even be popular for governments because they probably don't want to spend time rubber stamping EU legislation. I also wonder how the EU's legislative arrangements compare to other post-war vassal states. Did Germany and Japan have a legislative mess they needed to clean up when the Allied occupation ended?
