Screaming Channels - Response from Nordic?

Recently, the side-channel attack "Screaming Channel" was described in a paper (http://s3.eurecom.fr/tools/screaming_channels/).

The authors demonstrate a remote, passive, side-channel attack on nrf52 that allows data to be compromised if the processor handles sensitive data at the same time as the chip is transmitting over the radio.

Is there any official response from Nordic on this? In particular, it would be of interest to hear their view on the countermeasures described in the paper, Section 7.3.
