Yep, it's all good. In my opinion, IPv6 routers should just be dropping incoming connections by default. If you want to run services you give your machine a static IPv6 and open ports on that IP/port specifically. It's actually easier than NAT because you don't need to translate ports and each IP can use the same ports (multiple web servers on 80/443).
I do agree that the average joe is going to expect NAT level security by default and that would provide that.
