I suppose so but BFD certainly has alot more moving parts then adding
MDF checksums to an existing control packet.  I'm not saying everyone
should turn it on or off for that matter.  I just don't see what the
big deal is.  Most of the shops I've seen have it on because of some
long forgotten engineering standard.

Unfortunately, Network Engineers are lazy, impatient, and frequently

While the quantity of peering sessions I've had is far less than
yours, once upon a time when I had tried to get MD5 on dozens of peering
sessions I learned quite a bit about those engineers and those
networks.  I got to find out who couldn't do password management, who
never heard of MD5 and who had been listening to Patrick.  :-) All good
input that inform what else I might want to do to protect myself from
those networks or who I wouldn't mind having a business relationship
with.
