Good suggestion, I'll add something like that to the resumption section in 
draft-ietf-emu-eap-tls13

That seems like it could be a security problem in some implementations as 
cross-method resumption is not discussed anywhere and TTLS and PEAP says that 
inner-tunnel authentication is skipped for TLS resumption...

Your planned document on TLS 1.3 for other EAP methods should have some text 
describing this. Rather that forbidding cross-method resumption for TTLS and 
PEAP, I assume one could just specify that inner-tunnel authentication must be 
done after cross-method resumption. Or?
