Unfortunately, it is not. Some of the EAP operation events are still
available only through the (non-D-Bus) control interface and this new
message is in that category.

Agreed. Someone would need to define a suitable extension to the D-Bus
events to make this information available from wpa_supplicant and
matching changes in NetworkManager to be able to display this. Some of
the related events are available as D-Bus signals (e.g., as far as TLS
certificate validation steps are concerned), but I don't think there is
any generic event signal that would allow wpa_supplicant to make NM
display something all the way to the user in a reasonable manner today.
