Based on what I've read from RFC8620, their approach is quite smart. It's basically turning email protocol into a set of HTTP RPCs, thus shifts all the transport-related technical problems away.
The downside is that, JSON codes creates redundancy, sometime the redundancy is bigger than the meaningful data itself. But on the other side, you can now host an email server behind a web CDN. I like the development overall.
