I would not say it is more difficult, but clearly this is less common
use case for TLS.

Yes, I was planning on implementing this in the reverse direction for
testing EAP peer side similarly to what I've already implemented for
number of other TLS issues. It should be straightforward to extend the
design to work against EAP server side as well so that this would be an
option in eapol_test.
