Support for MQTT version 5.x ?

[Anders-Fromell-ITxPT]

Is there any plans to create a lib for mqttv5 client?
I must use a client with v5 support sinse consumers expect "content type" set as well as "user properties"(key/valuse) in header data

also I urgently need support for a client that let the broker assign a clientId, meaning client do not provide a clientId at connection, it will get one assigned by the broker in the conACK..
This is a way to avoid client "ping-pong" where two clients using the same clientId, and kick eatch other out while reconnecting.

Best regads,

Another urgent missing feature is the support of "request / responce" messages with the "responce topic" included in the request..
Many new API's and implementations states v5 "only" compliance including it's new security features..

I noticed that there is a initial seed of implementation in Micropython by Peter Hinch, link: https://github.com/peterhinch
