No, I was not aware of it. Yet, if I understand the objective of the Emacs ML and Debbugs, it is for, when you have a crash with emacs or, at least, an error stack trace when evaluating some lisp code. This is different from the intent here to define how to switch a thread started as a simple conversation to a tracked conversation, as a bug, feature request or suggestion, an the other way around.
Sorry if I was not clear about it or if I misunderstand the purpose of Debbugs and the Emacs ML.
