Should the default snapshot length in tcpdump be 65535?

The "tcp" in "tcpdump" is a bit old - people use it for doing more than just looking at TCP headers these days - and it sounds as if the problem Torsten Krah had tring to decrypt ipsec traffic was due to the packets being cut short by a snapshot length.

Would it make sense to have tcpdump default to the maximum snapshot length, rather than 68 (without IPv6 support) or 96 (with IPv6 support)?
