These are very useful when somebody else tells you which one applies to you, and you end up with a reasonably simple standard to check against. Finding the right damn standard, and checking that all the countries decided to implement it in ways that don't introduce random technicalities (in other languages) is very hard. So now you are weighing up the cost of investigative lawyers against the cost of being taken to court. And lets be honest, there are a lot of countries in the EU with not so many clients in them. So these are a completely non-legal safety net that is kind of legal but really isn't but probably won't cost you too much if you are wrong. Law is... hard.
