R191 release notes - Private Packet splitting

In the release notes for r191 there is a reference to the following new feature:

Supports LPTP protocol RAK private packet splitting / assembling protocol

Would I be correct in thinking this is for allowing shared private and public backends?

This is a private functionality of RAK for packet splitting in node and assembling in gateway side. It will be used for big packets to be sent without breaking the regulations of Alliance or law.

ahh ok thanks for the explanation @velev
