I would control traffic by giving ppp0, ip6test, and lo interfaces IPv6 addresses, and not giving IPv6 addresses to the interfaces you do not want to send/receive IPv6 traffic.
IME if you enable IPv6 in the kernel, EVERY up interface will have an IPv6 address (the link-local one, I suppose).
Also, without IPv6 enabled, it won't receive IPv6 packets on those interfaces.
Are you asserting that if IPv6 is enabled in-kernel, but an interface has no IPv6 address, IPv6 traffic arriving on that interface will be dropped on the floor? What about broadcast traffic?
