Indeed that is correct. The problem that I had described probably will almost never occur I assume.

I am not sure if that is correct... I "think" that cloning of messages might be a new kind of _ **hook** _, but I may be completely wrong!!!! The message hooks have been introduced via [this](https://github.com/node-red/node-red/pull/2665) pull request. But as you can see [here](https://discourse.nodered.org/t/live-stream-about-pluggable-message-routing-some-questions/30508/14) it is not decided at the time being how/if custom cloning would fit into this picture...

BTW you can read [here](https://github.com/node-red/designs/pull/7#discussion_r460817660) that cloning happens between the `preRoute` and `onSend` hook.

I try to avoid mentioning @knolleary as much as possible, but I'm afraid he is about the only one that can judge whether you are heading in the right direction...
