Yes it’s making the ticket system much simpler. But I don’t think this was top priority. For the 9€ ticket the rule seemed to be like „you can use it everywhere locally and additionally nationally for all trains which are not ICs or ICEs“ but in reality there were still some routes where you were not allowed to use it even though the train you use is an RE. Afaik you could not know except you were looking into the terms and agreements of the Deutsche Bahn. There are two reasons why the ticket system was (and probably partially will still be) so complicated: first we have a lot of transportation companies. Each city/region has their own. And we have the Deutsche Bahn - which responsible for all the national tracks and trains. They all have their own ideas of pricing and they never appeared to be willing to work together. Also, you‘d need a good electronic system to cover all the data from all these companies to work with them but this requires some degree of digitalization which Germanys is not capable of. It’s a mess :(
