While I don¹t fully understand the context of this particular test and the
scaling limitation, there are merchant silicon, NPUs and even CPUs that do
support MD5 and SHA
at transport line rate requirements.  BFD requirements are just a fraction
of these capabilities.

The option to negotiate capabilities should be available independent of
scaling/cost/inefficiencies at present time.  It is a matter of
implementation/product design choice.
