It does not enable "minimal RADIUS". No RADIUS functionality is used for
the authentication when the integrated EAP authenticator is used
directly from the IEEE 802.1X/EAPOL state machines.

The authenticator you are talking about is IEEE 802.1X authenticator.
EAP authenticator is the server side endpoint for EAP authentication.
The name "eap_authenticator" is used because it enables functionality
called "EAP Authenticator".

It has _nothing_ to do with RADIUS. Many RADIUS authentication servers
implement EAP authenticators, but so does many Diameter servers, and so
does EAP "servers". RADIUS is just one option for transfering the EAP
