I think that it's validation of QoS that really matters now. If I were to base on this recent video from Keysight <https://www.keysight.com/zz/en/events/america/webinars.html?D2C=2036435&isSocialSharing=Y&partnerref=emailShareFromGateway> (warning: requires registration), then it seems that there's a lot of emphasis on making grounded claims about the QoS that the operator sells.
