SAML2 is a growing, modern authentication method requiring little setup and knowledge and next to no maintenance to keep running. And, it's cloud-focused. RADIUS is an old, inflexible method that generally relies on either maintaining your own on-prem system or going to an expensive third-party "cloud" solution. Given Meraki is better suited not towards large enterprises but towards smaller, cloud-focused businesses, it would be in Meraki's best interest and follow their business model to move to support SAML authentication for 802.x. It would not make sense for Microsoft to implement an outdated authentication model in their cloud-focused Azure platform. Meraki/Cisco is also small-beans compared to Microsoft, so if anyone is going to follow suit it'll be Cisco. I mean, technically it's already possible by standing up an on-prem or cloud NPS server with RADIUS, but the goal of this post is to get Meraki to support modern technologies, so I find your comment out of place.
