It's not surprising. If you're first to adopt something by the time you realize how it could be improved you're locked into what you did. It happens with all kinds of early adoption. I noticed it a lot in Japan which picks up tech really quickly but as a result has been left with a bunch of crufty old systems. Like they were way ahead on contactless payment, but now they have a bunch of complex and confusion payment systems and lots of them don't support credit cards while the rest of the world just has contactless credit cards.
