I'll have to think about that a little more before I understand the underlying objection. From what I can see, MSK and EMSK are specific to EAP-TLS. They are derived in the EAP-TLS application, by passing EAP-TLS parameters to TLS key exporters. So the TLS layer has no concept of what MSK or EMSK are. As a result, the TLS layer should have minimal input into what those keys are, or how they are derived.
