I believe the bit.nl 6to4 gateway still generates IPv4 packets with non-routable source addresses, which are uRPFed by some operators.
At ISC, we have an unusually large population of external users using 6to4 to reach us, since most things we host are available on v6, and also because most things we host are of interest to developers who probably have more energy for turning things like 6to4 on than most people.
Our 6to4-using client population became much more happy once I deployed a 6to4 relay router inside AS3557, and had people use it directly instead of the anycast 6to4 relay router address. I don't think I've had a single complaint reported since I turned that on, in fact.
Advertising 2002::/16 and 22.214.171.124/24 for global transit from AS 3557 is on the to-do list. No ETA for that right now, however.
