There was an earlier email about when one would want to use the symmetric key exchange as outlined in the CCNxKE talk Chris Wood gate at IETF 94.  Another use case that we didn't mention is anytime you want to use HMAC signing, such as in IoT applications.

It's generally a bad thing to put raw keys out on devices and keep using those over long periods.  It's much better to use a key exchange protocol to derive symmetric keys and use those for signing.
