There's also the question of IP options (or extension headers). 8-)

I know that some modern hardware-based routers have the ability to either ignore options, or to drop option packets 
altogether.

I believe the same is now true of IPv6 extension-headere, or soon will be.  You're absolutely correct that this is a 
significant possible attack vector, causing the packets in question to be punted, if there isn't a mechanism available 
to ignore them or to drop said packets.
