Idk the second commit of the PR is much less important, but in a very data limited environment this could make sense if you are reopening the MQTT connection very often

Ah good catch!

There is similar logic for this like this in the repo:

https://github.com/TheNeikos/cloudmqtt/blob/fdcfb587d4ce0ea6ff289de66ab1169554758871/mqtt-format/src/v5/packets/puback.rs#L58-L68

Do you think you could adapt it to this?

true, looks better :). Done

Thank you!
