While I wouldn't recommend general use of such a mode of operation I do 
see some special situations where I think it could be necessary, even on 
my own network, especially in networks or subnets with high security 
requirements.

More fundamentally, I would prefer to see a graceful mechanism to 
achieve this policy, rather than requiring traffic filtering or another 
blunt force mechanism to achieve such a policy.  If someone feels they 
need such a policy they will find a way.  I believe it is far better for 
the protocol to give them a way to achieve their policy goals then to 
force them to use other possibly more drastic mechanisms to achieve 
their policy goal.
