Given that Release 15 does not require this extension, it only requires RFC 5448 EAP-AKA’ (or the bis), this means that there will be lots of phones and networks that only do the base… if you mandated an extension you’d have lots of users having a problem connecting. 

  Sure.

> It is not completely unthinkable that at some point you’d be in a situation where there’s enough deployment to start requiring something, but that would certainly be many years away. Plus some portion of 5G deployment happens in so called Option 3 model, which means no new core, no new protocols (incl. EAP) between the network and the UE. Before you can progress away from that and the RFC 5448-only modes, much time will pass.

  I've been doing my thing for 20 years.  I'm not going anywhere, so I'm thinking about the long term.

  Anyways, I think this is necessary.
