Most IPv6 transition mechanisms involve some form of (CG)NAT. After watching a NANOG presentation on MAP-T, I have a question regarding this.

Why isn't MAP-T more prevalent, given that it is (almost) stateless on the provider side?

Is it CPE support, the headache of moving state to the CPE, vendor support, or something else?
