After some more reading it seems this isn’t a decision by the EU but the members of the Bern Convention which the EU members are just part of. Some African and American countries are also members of that.
As for decision by the EU: only decisions effecting trade between countries seem enforceable, internal policy can’t be forced by the EU on member countries, it’s a choice to adopt EU laws. Like for example the EU copyright directive was passed in 2019 and only 4 member states chose to adopt it to this day.
