much of it is a lot of hard work getting to support TLS 1.3, which is nice. I have some TLS-dependent things in prod and let me say, it is really easy to do TLS in OTP. It's also easy to do TLS wrong in OTP, so I recommend watching all of Bram Verburg and Ingela Anderton Antin's videos first.

the socket library (if I am correct) is the beginning of redoing the entire network stack in a way that is more commensurate with the way that typical programmers expect (but with the right erlang-ey).

This is kind of huge. Sometimes you want a locking, fully consistent process management (so CRDTs are inappropriate), and you don't want a full raft/paxos under the hood.
