No, you're mistaken.

I said nothing about what the iSCSI devices IMPLEMENT.  I only talked
about what was IN USE by the customer.  In the example, the customer
chose to USE a different security mechanism for reasons of cost,
convenience, site policy, or whatever.

Remember that the proposed requirement is "required to implement" and
NOT "required to use".

My interpretation of having "use" be optional is that you also have
the option of securing your traffic via other means.  

Am I right?  Or is it the intent of the WG to say that no other
security mechanisms are allowed -- if you want security you MUST use
the one that is mandated in iSCSI nodes?  If so, for what reason?
